Sneha Basak, PhD

I had the pleasure of working with John during my Ph.D. at Stony Brook University in Dr. Peter Tonge’s lab, collaborating on several projects. He is a very organized, analytical, and cooperative person with a positive attitude. His knowledge and critical thinking abilities have helped accelerate progress on different projects. In addition, he has excellent communication skills and is willing to go the extra mile to help when needed. Moreover, due to his outstanding leadership qualities, he was able to lead several projects and mentor numerous undergraduate and graduate students in the lab.

I worked closely with John during his time at Stony Brook University completing his Chemistry Ph.D. in the Tonge Lab. John was an instrumental mentor as he was always open to discuss protocols and procedures, nuances in the projects, and especially break down any aspects of work he did to ensure it was clear and concise to be repeated. His dedication to his work aided in pushing numerous projects forward such as his PK/PD modeling work and our joint project on breast cancer research. John communicates very well to ensure the progression of the project and fulfilling his role on the team. John is a reliable scientist and it was a pleasure to work with him during our overlapping time at Stony Brook. He would make a very strong addition to any project and team.

      I worked for AMI as a research associate at the South Dakota Business Technology Center in conjunction with the University of South Dakota Biomedical Engineering Lab at the GEAR Center. I synthesized and characterized antimicrobial latex emulsion polymers. I worked to fulfill a quota of synthesized polymer for an industrial client for use in antimicrobial paints. During this synthesis, I modified the method and performed method development as the reaction was scaled up to 32.5X. During synthesis I was trained in acrylamide polymer synthesis, characterization using dynamic light scattering particle analysis. I also synthesized antimicrobial silica hybrid nanoparticles for incorporation into plastics with various potential antimicrobial uses particularly in the food processing industry. This quota of silica hybrid nanoparticles was to be used to fulfill a proof of concept for a phase II SBIR Grant. Working for a small start-up offers instruction at the intersection of the physical sciences and business. This opportunity also placed me in a position to be a part of the experimental design process, aid in problem solving, and learn directly from the CEO and Lead Senior Scientist.

      Undergraduate Research Fellow in the Mays Lab. The research group is interested in exploiting the myrosinase/glucosinolate enzymatic processes as a means of achieving selective drug candidate activation. During my time in the Mays lab I performed a multistep organic synthesis of 2,2-diphenylethyl glucosinolate, a precursor whose breakdown product is a known p53 inhibitor. I also gained experience in small scale organic chemistry, chromatography methods, spectroscopic analysis, and experimental design.
