Our Team

Dr. Chu received her PhD degree from the University of Hawaii at Manoa with specialties in tropical medicine and medical microbiology. Dr. Chu’s public health career was with the CDC where she served in multiple roles including being the Director of the CDC’s system-wide laboratory enterprise. After leaving CDC, she returned to Colorado and now holds a clinical professor appointment at the Colorado School of Public Health. Concurrently, she works as senior technical consultant for USAID and WHO. Among her multiple roles for CDC, Dr. Chu was assigned to the WHO participating in the Global Outbreak and Response team, deploying for multiple outbreak responses to SARS, viral hemorrhagic fevers, pandemic influenza and natural disasters. She also led the biosafety and laboratory network activities for the WHO International Health Regulations team. She was assigned as the assistant director for public health to the White House during 2014-2015 where she was an integral part of the President’s Ebola Task Force and coordinated the national reform on the Select Agent Rule. Currently, she is working with UNICEF/USAID on the delivery of Zika virus point of care diagnostics and with WHO on improving protection for healthcare workers fighting high threat pathogens (Ebola, influenza and respiratory diseases). Since February 12, 2020, Dr. Chu has joined the WHO experts group for infection control and prevention for the COVID-19 epidemic.

Dr. Jaenisch is an Infectious Disease Epidemiologist and Clinical Scientist. For the last 20 years, he has coordinated multicentric observational clinical research projects on arbovirus infections like Dengue or Zika.

His research was instrumental to provide key evidence for the WHO Dengue classification of 2009. After that, he focused on warning signs for severe Dengue and on standardized severe disease endpoints in Dengue. When the Zika epidemic hit Latin America in 2016, he was able to use the existing network of partners to mount a research response against Zika. 

Dr. Jaenisch was involved in large multicentric pregnant women and children cohorts in Latin America as well as in Data Sharing and Harmonization of Infectious Disease cohorts, building on the ongoing Zika birth cohorts. He has expanded to working on transmission of respiratory pathogens in congregate settings (for example schools) locally.

Dr Jaenisch was trained as a Medical Doctor in Germany, has obtained a PhD in International Health at Johns Hopkins University Bloomberg School of Public Health, and has worked in Tropical Medicine and Global Health at Heidelberg University Hospital from 2005-2019. He serves as the Director of the Arbovirus Research Consortium, located at the Center for Global Health at the Colorado School of Public Health.

Dr. Lamb's research and public health practice are focused on improving the health of children living both in the United States and in resource-poor countries. Before joining the faculty at the Colorado School of Public Health at the CU Anschutz Medical Campus in 2011, she was an epidemic intelligence service officer with the Centers for Disease Control and Prevention, stationed at the National Center for Health Statistics in Hyattsville, MD, where she investigated infectious disease outbreaks and conducted research on childhood obesity. She currently is an clinical teaching associate professor in the department of epidemiology as well as an epidemiologist at the Center for Global Health, where she works on research and public health projects in Guatemala and India, and serves as the director of educational experiences, linking students with global health projects and mentoring junior global health researchers. She is also the director of the DrPH in Epidemiology program at the Colorado School of Public Health. She specializes in designing and conducting multi-site and international longitudinal surveillance and epidemiologic studies, and conducting advanced epidemiologic analyses on the complex data these studies produce. She also focuses on teaching global health courses and mentoring junior colleagues from marginalized populations, disadvantaged groups, of minority status, and who are focused on health issues disproportionately affecting the world’s poor and disadvantaged populations. 

As the Director of Educational Experiences, she support students and junior colleagues in getting involved in global health research and public health projects. As a co-Instructor of the Global Health and Disasters course, she collaborates with clinical colleagues to design and present this survey course of relevant global health topics to medical students and residents, and bring public health expertise to the course. And as an epidemiologist, she works with the Trifinio team and the India team on designing, running, and analyzing their epidemiologic research studies and public health programs. 

Over the past year she has continued her long-standing collaboration with the Trifinio team conducting infectious disease research in the agricultural workers and their families living near the study site in rural Southwest Guatemala. She has also continued to provide epidemiologic support to the TEALEAF interventional trial that aims to develop a sustainable approach to addressing the mental health needs of grade school children in Darjeeling, India. In addition, she have been involved in a variety of educational activities, including mentoring graduate students, teaching graduate-level global health courses, and researching the effectiveness of global health training activities.

Dr. Olson is an associate professor in the Section of Infectious Diseases (ID) at the University of Colorado (CU) School of Medicine, with secondary appointments in the Department of Epidemiology within the Colorado School of Public Health and the Department of Bioengineering in the CU School of Engineering. His research focuses on novel approaches to emerging infectious diseases (EID) surveillance, including field-based molecular diagnostics, measuring the clinical and socioeconomic impact of EIDs in resource-limited populations, as well as the immunologic response, and assessing the benefit of community-based interventions such as vaccines. He is the co-director for research at the CU-associated Center for Human Development in Southwest Guatemala, and he leads several cohort studies with a number of collaborators from CU, Colorado State University, the Centers for Disease Control and Prevention, and elsewhere. Dr. Olson teaches in the Colorado School of Public Health and is the Global Health Fellowship director.
