Michael Walsh, PhD, MPH

Assistant Professor

Department of Epidemiology and Biostatistics

Tel: (347) 557-1108 • Fax: (718) 270-2533


Academic Qualifications:

  • PhD: University of Pittsburgh
  • MPH: University of Illinois at Chicago

Background and Expertise:

Dr. Walsh is an Assistant Professor of Epidemiology and Biostatistics in the School of Public Health. He received his PhD in epidemiology from the University of Pittsburgh and his MPH from the University of Illinois at Chicago. Dr. Walsh was a co-founder of the Swasthya Community Health Partnership in Sringeri, India. This five year project trained community health nurses to serve the unique health needs of women in this rural community in southern Karnataka. Dr. Walsh’s specific research focused on human papillomavirus infection and cervical cancer during his time with Swasthya, and on a tuberculosis eradication project among the indigenous Soliga communities in the B.R. Hills prior to that. Subsequently, Dr. Walsh worked on diabetes and its microvascular complications with the WHO DiaComp Study and the Epidemiology of Diabetes Complications Study in Pittsburgh, both under the direction of Dr. Trevor Orchard. Several important publications resulted from this fruitful research. Upon completion of his PhD, Dr. Walsh went on to work with the New York City Department of Health and Mental Hygiene’s NYC Health and Nutrition Examination Survey. Following this he joined the faculty of New York University where his research focused on biosurveillance of nosocomial infection and musculoskeletal disease. Dr. Walsh currently conducts research in helminthiases and arthropod-borne infections with a particular focus on the landscape epidemiology of toxocariasis and West Nile virus.

Areas of Research:

Dr. Walsh is an infectious disease epidemiologist. He is interested in the complex ecologies of human pathogens and the ways in which specific pathogens interact with hosts, vectors, and environments in the multi-dimensional space of the living surface that comprises the landscape of infection. As such, he is a strong proponent of applying a landscape approach to epidemiologic investigation, which combines spatial analysis with layered ecologic analysis and epidemiologic methods to explore associations between exposures and outcomes. Dr. Walsh currently has two primary research areas.

First, he is exploring the occurrence of toxocariasis in the urban environment and its potential association with poor lung function and poor cognitive development in children.

Second, he is studying the relationship between arthropod-borne and zoonotic infections and hydrogeography, forest fragmentation, and climate in New York State.
