Michael Walsh, PhD, MPH


Michael Walsh is a landscape epidemiologist with the Marie Bashir Institute for Infectious Diseases and Biosecurity at the Westmead Institute for Medical Research. He is interested in the complex ecologies of zoonotic pathogens and their interaction with hosts, vectors, and environments to shape risk. As such, he applies methods from traditional spatial epidemiology, as well as more modern applications of biogeography, ecology and geocomputation to inform infectious disease inference and prediction. Michael is particularly interested in the ways in which interactions among wild and domesticated animals in anthropogenically altered landscapes facilitate pathogen spillover from primary reservoir hosts to novel hosts. Michael has 19 years’ experience as an epidemiologist and is currently investigating the landscape epidemiology of Ross River virus and zoonotic pathogens in pastoralist communities. Michael has taught infectious disease epidemiology and epidemiology methods for 14 years on the faculties of New York University, the State University of New York, Downstate, and, currently, at the University of Sydney. Senior Lecturer in Infectious Disease Epidemiology. ORCID: orcid.org/0000-0002-6441-3635

Philippe Amstislavski, PhD

Philippe’s overarching interest is to improve our understanding of socio-ecological systems through analyses that appreciate their full complexity. He is especially interested in landscape epidemiology, environmental change and community resilience in the Circumpolar North. His current research examines the impact of changes in hydrologic cycles on subsistence-based communities and spatial clustering of disease cases. In this work he focuses on data analyses that comprise the health, social and environmental layers of disease landscapes. He also leads sustainable bio-materials development team at the University of Alaska.

Philippe has been teaching GIS, spatial analysis, and environmental health course for the last 8 years. Currently, he is on the faculty at the University of Alaska, Anchorage.



Haseeb Siddiqi, PhD

Haseeb A. Siddiqi is professor of cell biology and pathology, appointments in the School of Graduate Studies, College of Medicine, and School of Public Health. An international authority in the field of tropical medicine, Dr. Siddiqi was recognized with the Chancellor's Award for Excellence in Faculty Service in 2014. He has served on Downstate's faculty since 1982.

Dr. Siddiqi's professional activities encompass teaching, research, and service, and range from instructing medical students and residents to conducting basic and clinical research, to serving on editorial boards and steering committees of national and international organizations, as well as on campus committees. He also serves as director of the clinical Parasitology and Diagnostic Immunology Laboratories at Kings County Hospital.

Over his years at Downstate, Dr. Siddiqi has actively promoted inter-disciplinary collaborations between the fields of microbiology, immunology, and pathology. His own laboratory work has involved collaborations with faculty at Albert Einstein College of Medicine, California State University at Long Beach, and the Swedish Institute for Infectious Disease Control, with a focus that includes schistosomiasis, to infections in AIDS patients, to malaria and sepsis. His research has been recognized and funded by a variety of distinguished agencies, including the World Health Organization (the United Nations' authority on matters of health and medicine.)
