Letter from the Head Dear Friends: This year is the 10th anniversary of the College of Public Health and the College has already begun its year of celebration. Our Department of Bio- statistics has continued to flourish and we have travelled a long way since the offering of the first course in “Biostatistics” at the University of Iowa in 1947: sixty-two years ago. The sound scien- tific foundation provided by the Department of Preventive Medicine and Environmental Health has led to a fully operational and mature College of Public Health. This year we welcome our new faculty member, Professor Chris Coffey, who is also Deputy Di- rector of the Clinical Trials Statistical and Data Management Center, and we welcome our nine new graduate students. Our incoming graduate students are diverse, coming from Illinois, Texas, North Dakota, China, Minnesota, Arizona, Wis- consin, and two from Iowa. We look forward to their success here in the future, as we wish our thirteen graduates in 2009 success in their future endeavors. The economic recession has resulted in financial challenges and hardships throughout the Univer- sity and the state of Iowa. Even as we face these diffi- culties, we are pleased that construction of the new College of Public Health Building continues to progress rapidly. Lower than anticipated construc- tion costs mean that the entire space for the five Departments will be fully finished when we move in. We look forward with great antici- pation (and, admittedly, some trepidation about change) to moving into the new College of Public Health Building: the biggest excitement is that faculty and students will be across the hall from each other, rather than a 10-minute walk away. As the economy recovers, we look forward to continued growth and development of our col- lege in its mission to provide quality education in public health and related areas and high quality research and service. Very best wishes, and thanks from everyone here, to our friends and alumni for their contin- ued support and interest,

And he has become engaged to Jennifer Froelich. Dawei Liu announced the birth of his son, Yiliang, on October 11, 2008. Jane Chalmers, wife of Knute Carter, MS ‘07, passed away at home with her family at her side on December 6, 2008, after a courageous fight with cancer. Wei Zhang, PhD ‘05, welcomed the birth of his son, Ryan, on January 19, 2009. Yang Xu, MS ’09, is the proud father of Christopher Hanwei Xu, born on July 12, 2009. Lei Hua, MS ’07, gave birth to a baby girl, Rachel, on August 18, 2009. Emine Ozgur Bayman, PhD ’09, and Levent Bayman, MS, ‘09, welcomed baby girl, Sedef Bilge, on September 19, 2009. Iowa Summer Institute in Biostatistics (The Iowa SIB) The Department is the proud recipient of a grant from the NIH NHLBI and NCRR to join the SIBS family of Sum- mer Institutes in Biostatistics. Fifteen to twenty selected undergraduates will come to Iowa to learn about Biosta- tistics through hands-on case studies and be encouraged to enter graduate school in Biostatistics. Our Iowa SIB (or ISIB) will build on our partnership with the Alliance and will focus on recruiting minority students through the Alliance: specifically undergraduates majoring in math or biology (or both) who are studying at colleges or univer- sities without an extensive statistics or biostatistics curriculum. The Iowa SIB will be directed by Gideon Zamba, with assistance from Jeffrey Dawson, Jacob Oleson, Brian Smith, and Phil Kutzko, Professor of Mathematics and PI of the NSF Alliance. The principal investigator is Kathryn Chaloner, who will also assist. More details, along with links to all eight SIBS can be found at http://www.nhlbi.nih.gov/funding/training/redbook/ sibsweb.htm . The Department of Biostatistics is starting a new tradition with an annual lecture denoted the “Woolson Lecture”. Each year, a distinguished biostatistician will be invited to give a lecture on a topic of high current interest in biostatistics. The inaugural lec- ture will be given on April 19th , 2010 by (very appropriately) the founding chair and long time Division Director, Robert F. Wool- son, PhD. Inaugural Woolson Lecture The University of Iowa has announced that all alumni will have access to RefWorks as long as the institution has a subscription. This applies to both alums who created accounts when here and alums who want to create new ac- counts. The Library has delayed formally announcing this since they are unsure of the best way to share group codes since alumni cannot use the proxy server to connect or access the current group code. When they figure it out they will make an announcement. Meanwhile they are manually giving out the group code RWUI10 to use RefWorks.

BSI was created with the goal to increase the number of underrepresented minority students in our graduate program. The program trains selected undergraduate students, with math, biology, and/or sci- ence backgrounds, who are likely to be- come future biostatisticians. The program is run in conjunction with The National Alli- ance for Doctoral Studies in the Mathematical Sciences. The BSI offers seven weeks of summer training, including a five-week introduction to biostatistics course followed by a two- week research internship. Selected stu- dents for the BSI receive a scholarship ei- ther through the Alliance program or through the Department of Biostatistics. Students are supervised by a Biostatistics faculty member and assisted by a graduate research assistant who also provides help with their internship research projects. The projects give students exposure to research and opportunities to see medical science in action through biostatistics. After the supervised research, students present their accomplished research to faculty and other students at an Alliance meeting. The BSI is coordinated by Drs. Gideon Zamba, Jacob Oleson, Brian Smith, and Kathryn Chaloner. The 2009 cohort had six successful and talented students: Phyon Christopher, Jamie Encarnacion, Tenecia Harris, Christopher Johnson, Leondra Lawson, and Keyla Pagan-Rivera. In 2010, this program is an NHLBI- sponsored training program, the Iowa Summer Institute in Biostatistics (ISIB). If you know of any underrepresented minor- ity undergraduate students who may be interested in our summer program, please refer them to our website at http:// www.public-health.uiowa.edu/biostat/ current_students/bsi/ or contact Gideon Zamba at gideon-zamba@uiowa.edu or Terry Kirk at terry-kirk@uiowa.edu. Biostatistics Summer Initiative 2009
  7. 7. P A G E 7 Message from Dean Susan Curry As the College of Public Health acknowledges its 10th anniversary during the 2009-10 academic year, it is not difficult to recognize the leading role our Depart- ment of Biostatistics has played in the college’s growth and development. Since our inception in 1999, our college has benefitted from the outstanding leadership of biostatisticians, such as Robert “Skip” Woolson and Leon Burmeister, each of whom has served in Associate Dean capacities. An established research powerhouse, the department has a well-deserved reputation for critical contribu- tions across a range of disciplines that intersect with public health, from the work of Bill Clarke in dia- betes to Jeffrey Dawson’s studies to assess elderly drivers. The de- partment’s strong commitment to student mentoring and teaching is evidenced by biostatistics faculty who have received the College of Public Health’s Outstanding Teaching Award: Joe Cavanaugh in 2006 and Ying Zhang in 2008. Through projects such as the Iowa Health Fact Book, led by Jacob Oleson and Jane Pendergast, the de- partment has been a leader in providing essential health information to health practitioners, policymak- ers, and researchers across the state. And recently, the Department of Biostatistics has again provided critical leadership for our college in the area of diversity initiatives. The Biostatistics Summer Initiative, led by Kathryn Chaloner, Jacob Oleson, Brian Smith, and Gideon Zamba, is a seven-week program that provides biostatistical training and ap- plied research opportunities for underrepresented mi- nority students. In 2009, Kathryn Chaloner received our Board of Advisors Award for Achievement in Community Engagement in recognition of her efforts to develop a collegiate culture that is welcoming of people from all backgrounds. As we look to the future of public health, one of the many reasons to be optimistic is the strong tradition of research excellence, interdisciplinary collaboration, and commitment to inclusiveness that is so evident in our Department of Biostatistics. Christopher S. Coffey, Ph.D., Professor of Biostatistics and Deputy Director of the Clinical Trials Statistical and Data Management Center, joined the Depart- ment of Biostatistics on July 31, 2009. Dr. Coffey received his Ph.D. in biosta- tistics from the University of North Carolina at Chapel Hill in 1999. He re- ceived both the 2000 Barry H. Margolin Award for excellence in doctoral re- search and 2005 Grizzle Distinguished Alumni Award from the Department of Biostatistics at UNC. He spent the last eight years on the faculty in the Depart- ment of Biostatistics at the University of Alabama at Birmingham (UAB). During his time at UAB, Dr. Coffey served as the Chair of the Faculty for the School of Public Health (SOPH), served as the Graduate Program Director in Biostatis- tics, and taught courses in survival analy- sis, theory of linear models, and ad- vanced clinical trials. He won the 2004 UAB President’s Excellence in Teaching Award for the SOPH. Dr. Coffey has over 60 publications in both journals of statistical importance (e.g., Biometrics) and prestigious applied journals (e.g., JAMA). Dr. Coffey has served as the lead statistician on a variety of applied projects, with a particular in- terest in the coordination of large ran- domized clinical trials. He is the current chair of the education committee for the Society of Clinical Trials. Dr. Coffey’s primary research interests include design issues such as power and sample size calculations, sample size re-estimation methods, and adaptive designs. He has helped develop methods for implement- ing internal pilot studies that allow the use of pilot data in the final analysis and published on this topic (e.g., Biometrics, Statistics in Medicine, Communications in Statistics). Chris’ wife Beth is currently a stay-at- home mom. She previously worked as a data coordina- tor for the Women’s Health Initia- tive site at UNC and at the UAB Compre- hensive Cancer Center. They have two children. Thomson is 11 and enjoys history and video games. Barrett is 5 and simply enjoys being active. Chris is an avid runner and sports enthu- siast (he has already gotten hooked on Iowa football). On a lighter note, he is also a fan of professional wrestling and has worked on a storyline for the WWE as a backup for a second profession. Anyone who is interested can ask him about his storyline for “The Professor”. However, if you ask about it, be prepared to hear the storyline in vivid detail. Meet Chris Coffey
  8. 8. P A G E 8 D E P A R T M E N T O F B I O S T A T I S T I C S N E W S L E T T E R The College of Public Health will be celebrating its 10th anniversary during the 2009 -2010 academic year. And thanks to support from private donors, in partnership with the University, the State of Iowa, and federal funding, we are anticipating the completion of our very own building. We will also publicly launch a campaign to raise private funds for the facility called the Building Today for a Healthy Tomorrow campaign. This $15 million fundraising goal includes $6 million for building con- struction and $9 million for faculty, student, and program support after the building opens. Ground was broken last year for the new facility which is scheduled to be com- pleted in late 2010. The new building, composed of glass and limestone and located on the site of the former International Center, will have 130,000 square feet of space and will integrate “green” design features, showcasing sustainability and envi- ronmental awareness. “The new building will help ensure an exceptional education for the leaders who will be faced with solving tomorrow’s critical public health issues,” says Dean Susan Curry, who began in her leadership role in August 2008. The College of Public Health has completed one full decade of providing students with a world-class public health education, and pursuing research and service activities that touch thousands of citizens both close to home and around the globe. College of Public Health’s 10th Anniversary
  9. 9. P A G E 9 Faculty News In recognition of her work promoting diversity, Kath‐ ryn Chaloner, Ph.D., Professor and Head, received  the College of Public Health’s award for faculty  achievement in community engagement on June 18.   This award is conferred annually by the Board of Advi‐ sors and recognizes a faculty member for application  of theory, research, and practice to address public  health challenges at the community level.    “Dr. Chaloner has undertaken impressive initiatives to  ensure continued growth in the number and diversity  of graduate students enrolled in the college, “ said  Stephen Ummel, chair of the College of Public Health  Board of Advisors.  “This award acknowledges her  committed and enthusiastic leadership to ensure that  the college’s diversity programs are an integral part  of a broader culture — a culture that is welcoming  people from all backgrounds.”    Dr. Chaloner worked to found the Biostatistics Sum‐ mer Initiative, a seven‐week program that provides  biostatistical training and applied research opportuni‐ ties for underrepresented minority students.  This  program is offered in conjunction with the National  Alliance for Doctoral Studies in the Mathematical Sci‐ ences.      In the summer of 2008 the first group of four Biosta‐ tistics Summer Initia‐ tive students com‐ pleted their training.   One of those students  is now a doctoral stu‐ dent enrolled in the  Biostatistics program.   Carmen Smith is the  first African American  Ph.D. candidate in the  history of the depart‐ ment.  Six students  were enrolled in the  2009 summer program.   Dr. Gideon Zamba di‐ rects the summer program and Drs. Brian Smith and  Jacob Oleson serve as mentors.  Dr. Kate Cowles, As‐ sociate Professor of Statistics and Actuarial Science,  also mentored a student in the summer 2009 session.    In September, the Department of Biostatistics, to‐ gether with the Alliance, hosted the StatFest/Field of  Dreams Conference.  Underrepresented students at‐ tended this conference to learn about careers and  graduate studies in statistics and other mathematical  sciences.    Dr. Chaloner is a mentor for the National Alliance for  Doctoral Studies in the Mathematical Sciences, which  is a consortium whose goals include encouraging un‐ derrepresented minority undergraduates to pursue  graduate degrees in the mathematical sciences.  It  provides them with  the preparation and support to  pursue these degrees.  Phillip Kutzko, UI Professor of  Mathematics, leads the Alliance.      Dr. Chaloner’s research interests include using Bayes‐ ian decision theory and Bayesian statistics for the de‐ sign of experiments and clinical trials.  She collabo‐ rates on research in HIV/AIDS studies and in clinical  trials of islet transplants in people with Type I diabe‐ tes.  She is an elected fellow for the American Asso‐ ciation for the Advancement of Science and the  American Statistical Associa‐ tion.    See page 6 for a description  of our new Iowa Summer  Institute in Biostatistics.    Dr. Chaloner (back left) with 2009 BSI students

P A G E 1 0 D E P A R T M E N T O F B I O S T A T I S T I C S N E W S L E T T E R Dawei Liu, Assistant Professor of Biostatistics, and Ryan Carnahan, Clinical Assistant Professor of Epidemiology, were awarded the 2008- 2009 College of Public Health-Carver College of Medicine New Inves- tigator Research Award. The awards assist newly appointed faculty in the College of Public Health or the Roy J. and Lucille A. Carver Col- lege of Medicine to advance their research activities. Each recipient receives up to $10,000 of funding for independent research projects. The recipients’ awards were chosen on the basis of scientific merit, relevance to the College of Public Health mission, strategic plan and goals, and the probability of attracting subsequent extramural research funding. Dr. Liu’s winning research proposal was entitled “A Joint Modeling of Correlated Recurrent and Ter- minal Events with Multivariate Frailty in the Analysis of Driving Safety Data in Patients with Parkinson’s Disease.” Faculty News (cont.) Gideon Zamba, Assistant Professor of Biosta- tistics, judged a research competition at the Annual Biomedical Research Conference for Minority Students (ABRCMS) in Orlando, FL, last November. ABRCMS is the largest professional conference for biomedical students. This was the 8th year for this conference, which lasts four days and included more than 1,200 students participating in poster and oral presentations in biomedical and behavioral sciences. Dr. Zamba was one of three judges; those students receiving the highest scores in each scientific discipline and in each educa- tional level were given monetary awards of $250 for their outstanding research. The conference is designed to encourage underrepre- sented minority students to pursue advanced training in the biomedical and behavioral sciences and pro- vide faculty mentors with resources for facilitating the success of these students. This past year’s confer- ence included over 500 faculty and program directors and over 440 exhibitors. Dawson and Team Recognized for Driving Research Jeffrey Dawson, Professor of Biostatistics, and colleagues in the Uni- versity of Iowa Division of Neuroergonomics (www.uiowa.edu/ ~neuroerg/) received widespread recognition this year for their studies of drivers with neurological diseases. In the February 10th issue of Neurology, Dawson and coauthors reported the increase in safety er- rors made by 40 drivers with Alzheimer’s disease versus 114 elderly controls. They also showed which types of cognitive tests were pre- dictive of these safety errors, giving much-needed guidance to physi- cians and families who help decide when a patient with Alzheimer’s disease should no longer drive. “We found that tests which measured multiple domains of cognition were correlated with driving safety, whereas simple memory tests were not,” reports Dr. Dawson. “For example, being able to recognize and copy geo- metric shapes was predictive of safety, whereas the ability to memorize a list of 15 words was not as important. Unfortunately, there is so much variability in driving that we cannot propose specific cut-off values of cognitive tests that should be used as firm criteria for de- ciding when individuals should no longer drive. In the future, we hope to use in-vehicle
  11. 11. P A G E 1 1 Field of Dreams/StatFest Conference held on UI Campus The Third Annual Iowa Mathematical Field of Dreams Conference, sponsored in part by the Na- tional Science Foundation and held this year in conjunction with the American Statistical Asso- ciation’s StatFest Conference, allowed students to meet with representatives from graduate pro- grams across the country, talk with current graduate students, and explore career opportunities, including careers in public health. Around 90 underrepresented minority students from around the U.S. and 40 of their faculty men- tors met on the University of Iowa Campus September 25-27. The two events highlight academic graduate and career opportunities in the mathematical sciences. The Field of Dreams Conference is held by the National Alliance for Doctoral Studies in the Mathematical Sciences, an alliance among a group of mentors in the math/sciences depart- ments of the Iowa Regents Universities (Iowa State, University of Iowa, and University of Northern Iowa) together with several other gradu- ate departments in the math/sciences nationally and faculty members at colleges and universities that serve a large number of underrepresented minority undergraduate students in the U.S. The UI Department of Biostatistics co-sponsored the Iowa conference. The students learned about opportunities for fi- nancial aid and funding, what to look for in a graduate program, how to recognize a supportive environment, opportunities that come with a graduate degree, in addition to learning about the different math/science disciplines. Current students and faculty also shared their experiences and challenges of attending graduate programs and what is involved with moving from a minority school to a majority school. monitoring devices that would allow the cars themselves to be diagnostic tools, to supplement the infor- mation that can be obtained in a clinical setting.” Interviews with Dr. Dawson were featured in newspa- pers, television, radio, and internet reports, such as USA Today, the New York Times, the Miami Herald, CNN Health Reports, CBS News, and Scientific American Online. Current colleagues in the Division of Neuroergonomics include Drs. Matthew Rizzo (principal investigator), Steven Anderson, and Ergun Uc of the Department of Neurology, as well as PhD students Elizabeth Dastrup (MS, 2008) and Amy Johnson (MS, 2009). Some of the Puerto Ricans get together for a photo. The 2009 Iowa Health Fact Book is a broad-ranging report covering the health and health-related behaviors of Io- wans. Jacob Oleson and Jane Pendergast led development of the publication on behalf of the UI Center for Pub- lic Health Statistics working in collaboration with the Iowa Department of Public Health. New to the book this year is a section on “The Social Determinants of Health,” which focuses on behavioral conditions and coincides with the upcoming release of Healthy People 2020. Many of the data sets are presented by county so readers can follow Io- wans’ health and behaviors over time. To access the Fact Book online, visit www.public-health.uiowa.edu/ factbook.
