EDUCATION
Clarkson University, Potsdam, New York, USA
M.S. Environmental Science and Engineering Expected graduation: July 2015
 Thesis: Nutrient/materials recovery from anaerobic sewage sludge
P.E.S College of Engineering, Karnataka, India
Baccalaureate in Environmental Engineering Graduation: June 2013
PROFESSIONALEXPERIENCE
NYSP2I Project, Graduate Research Assistant, Potsdam, NY May 2014-present
Nutrient Recovery from Anaerobically Digested Food Waste Stream
 Currently using air-stripping, acid scrubbing and chemical oxidation as treatment methods for recovery of
ammonia and other nutrients from biosolid effluent.
 A counter current packed column was designed for the stripping process.
 On an average 85-90% of nitrogen in the form of ammonia was recovered from the air stripping treatment
process.
 Microfiltration and UV disinfection was done to ensure functionality in aeroponic sprayers and food grade
quality.
 Increased crop yields 5% using processed digestate effluent in a PLC controlled year-round high-rise
farm.
Local Living Venture, Volunteer, Potsdam/Canton, NY May 2014-November 2014
Association with the LLV mainly involved outreach and education to local communities
 Community workshops for rain-water harvesting that help understand the working and benefits of reservoir units
at individual homes.
RELATED PROJECTS
Treatment of leachate from a Class 2 Inactive Hazardous Waste Site
Potsdam/Salina Township, NY January 2015-April 2015
 This design project, with collaboration from CHA Companies required Environmental Engineering majors at
Clarkson to develop a remediation process and design a treatment plant for contaminated groundwater underlying
the Salina Town Landfill.
 The major contaminants in the landfill leachate were VOCs, PCBs and mercury, which seeped into the
groundwater. Flow-rates of the leachate were established at different sections of the trench.
 A pump station was designed that would convey contaminated groundwater leachate into a nearby wastewater
treatment plant.
 A wastewater treatment matrix along with cost analysis is being evaluated at present.

2. Assessment of the efficiency of microfiltration in conjunction with different pretreatment strategies for treating Raquette
river water, Potsdam, NY March 2014-June 2014
 The project investigated using microfiltration technique along with other pre-treatment methods like Alum
coagulation and sedimentation to achieve appreciable removal of natural organic matter in Raquette river water.
 Coagulant dose, pH and operation situation of coagulation-microfiltration system were optimized.
 Different pretreatment strategies were integrated in order to improve the performance of low pressure
membranes.
 The performance of low pressure membranes were defined in terms of water quality
Determined factors that affect methane production in a bench-scale food waste digester
Mandya, Karnataka, India December 2012-May 2013
 The project involved design of a bench scale digester for treating food waste samples from school (P.E.S College
of Engineering) cafeteria.
 Tested various parameters such as pH, temperature, VOC concentration that affect methane production were
tested.
 The role of seeding (cow manure) was also investigated that increased methane concentration in the gas over the
period of time.
Workplace hazard and safety assessment at Bengal Non-Resident Indian Urbana Project construction site
Kolkata, West Bengal, India September 2013-November 2013
 The project involved carrying out a detailed assessment of working conditions and the necessary level of
safety measures and practices in place.
 Workers involved in hot works, work at height and conditions at the cement batching plant were examined.
 General layout of pedestrian routes, vehicle routes, possible conflicts, adherence to wearing personal
protective equipment were observed.
