Lakota's research interests include substance use disorders, social behavior, and individual differences in placebo susceptibility.

Mumtahana Nabi, BDS, MPH

PhD Student (Molecular Epidemiology)

Mumtahana Nabi is a PhD student in Molecular Epidemiology at the University of Maryland, Baltimore School of Medicine. She obtained her BDS (Bachelor of Dental Surgery) degree from the Dhaka Dental College in Bangladesh. She also received two MPH degrees in Epidemiology from the University of Massachusetts Lowell and Northern University Bangladesh. Her prior research experience provided a strong foundation in both quantitative and qualitative analytical skills using SAS and R. She is passionate about understanding the role of genetic and environmental influences underlying pain mechanism, variation in pain perception and response to treatment, particularly in the orofacial region. Her long-term goal is to improve pain management for cancer patients in developing countries through a better understanding of interaction between genetic and environmental factors, especially those from disadvantaged groups.

James Cottam, BSc (Hons), MSc

PhD Student (Epidemiology)

James Cottam received his Bachelor of Sciences with Honours from the University of Edinburgh, UK, before completing a Master of Sciences at the London School of Hygiene and Tropical Medicine, UK. He performed his master’s thesis ascertaining the reliability of data measuring seasonal malaria chemoprevention coverage. James is currently a PhD student in Epidemiology at the University of Maryland, Baltimore. His current research interests include health disparities, social determinants of disease and differential responses to treatment.

Ankita Moss, BS

MD Student

Ankita is an MD Candidate at the George Washington School of Medicine and Health Sciences, with an interest in the psychobiosocial aspects of pain management and perception. She has a background in neuroscience research methodology as well as neuroethics. She hopes to connect her experiences at the Colloca lab with her medical training.
