MOLECULAR DISCOVERY / GENETICS / BIOCHEMISTRY
My expertise is in molecular discovery. Prior accomplishments include the development and implementation of
a live cell-based high-throughput drug screening platform, vaccine candidate discovery in mice and the
identification and characterization of genetic mutations (created through random and site-directed mutagenesis)
and proteins (both structural and enzymatic) on multiple platforms including bacteria, yeast, filamentous fungi,
the protozoan parasite, Toxoplasma, and in mice.
My technical savvy, strong work ethic, creativity and dogged determination make me an ideal, hit-the-ground-
running candidate for championing high value projects.
RELEVANT EXPERTISE AND ACCOMPLISHMENTS
◆ Discovered, characterized and investigated protein targets in the parasite Toxoplasma through
yeast two-hybrid screening, genomic and protein database mining, and mass spec analysis of affinity-
purified multi-protein complexes.
◆ Developed and implemented a live yeast-based high-throughput screening platform, and
multiple secondary assays (cytokine-detecting ELISA’s / kinetic analysis) to identify and develop
isoform-specific inhibitors and activators of human cAMP and cGMP phosphodiesterases for
therapeutic use.
◆ Generated, designed, managed, and mined large chemical compound datasets for lead
generation and development. Developed chemical inventory procedures and protocols.
◆ Routinely performed detailed molecular analysis of proteins, post-translational modifications,
protein-protein binding motifs, drug interaction mechanisms (kinetic analysis), and small molecules
using a combination of immunoassays, molecular biology, genetic and biochemical tools.
◆ Developed and implemented an expression library DNA immunization protocol and procedure
to isolate and characterize fungal vaccine candidates in mice.

RESEARCH EXPERIENCE
BOSTON COLLEGE
Molecular architecture and mechanisms of Toxoplasma gondii cellular division. Laboratory of Professor Marc-
Jan Gubbels, May 2009-Sept 2010.
The obligate intracellular parasite Toxoplasma gondii divides by an internal budding process wherein
two daughter cells form within the mother. The cytoskeleton of the parasite is complex, and serves as a
scaffold for daughter cell assembly. Using a combination of genetics (i.e., yeast two-hybrid screens) and
proteomics, I identified enzymes and proteins that interact with an essential and dynamic component of
the contractile ring that is required during daughter cell maturation. My recent work focused on a family
of phosphatases that participate with, and modify MORN1 during cytokinesis.
BOSTON COLLEGE
Discover, develop and commercialize small molecule regulators of cyclic nucleotide phosphodiesterases. Co-
Founder of Fission Pharmaceuticals, LLC with Prof. Charles S. Hoffman, 2006-2009.
Developed fission yeast-based high throughput screen for mammalian and Trypanosomal
PDE inhibitors and validated this screening platform on over 400,000 compound-enzyme
combinations at the Broad Institute. Designed and implemented a versatile compound
database through a collaboration with BC bioinformaticians. Developed novel
techniques to allow working with cGMP-specific PDEs, despite the apparent absence of
cGMP signaling in fission yeast. Discovered the first small molecule activators of cAMP
PDEs. Demonstrated that PDE7A/B and PDE4A/B subtype selective inhibitors retain
therapeutic anti-inflammatory effects in tissue culture models. Played a central role
initiating collaborations with academic laboratories interested in testing PDE
inhibitors/activators in animal models for tumor metastasis, diffuse large B cell
lymphomas, HIV/SIV infection and replication, apoptosis of human lymphoma cell lines,
and compound-protein co-crystallization studies. Co-Founded Fission Pharmaceuticals,
LLC and acted as CSO.
BOSTON COLLEGE
Genetic analysis of G protein signaling in Schizosaccharomyces pombe. Ruth L. Kirschstein National Research
Service Award, Laboratory of Prof. Charles S. Hoffman, 2002-2006.
Defined protein-protein interactions, and structure-function relationships that govern G
protein-mediated signal transduction of the glucose signaling pathway. This work led to
the identification of a Gα (Gpa2) binding site on the Schizosaccharomyces pombe
adenylate cyclase enzyme and was the first work to describe a direct physical interaction
between a Gα subunit and adenylate cyclase in any fungal system.
In a parallel project, a genetic screen was conducted to isolate mutant Gα alleles that
promoted Gβγ-independent activation of the glucose/cAMP signaling pathway. Thirteen
novel, constitutively activated Gα variants were identified and characterized by in vivo
and in vitro assays. These experiments provide details into the mechanism of Gα
activation and define critical residues within Gα proteins that were previously unrealized.
UNIVERSITY OF TEXAS HEALTH SCIENCE CENTER-SAN ANTONIO
Valley Fever vaccine development. Postdoctoral Fellow, Laboratory of Prof. Rebecca A. Cox, 1999-2002.
At the South Texas Center for Biotechnology in Medicine, with Profs. Rebecca Cox and
Mitch Magee, I focused on vaccine development against the highly pathogenic fungus,
Coccidioides immitis, the agent of Valley Fever. I championed a procedure called
Expression Library Immunization and isolated a gene, ELI-Ag1, that protected mice

against a lethal challenge with C. immitis spores when administered as a DNA-based
vaccine.
UNIVERSITY OF TEXAS MEDICAL SCHOOL-HOUSTON
“Functional analysis of GNA-1, a Gαi superfamily member found in the filamentous fungus Neurospora
crassa.” Ph.D. Dissertation, Laboratory of Prof. Katherine A. Borkovich, 1993-1999.
My dissertation focused on G protein-mediated sensing in fungi. I provided the first
biochemical evidence, in any fungal system, for positive regulation of adenylate cyclase
by GNA-1. Discovered a mechanism by which intracellular cAMP levels are maintained
by compensatory mechanisms involving a balance between PDE and adenylate cyclase
activities. Reconstituted G protein-regulated adenylate cyclase activity through mixing
experiments between G protein and adenylate cyclase mutant membrane extracts.
