CDUHR Seminar – Magdalena Cerdá – March 12, 2024
Tuesday, March 12, 2024, 10:30 am-11:30 am
Location: Zoom webinar
Presented by: Magdalena Cerdá, DrPH, MPH
Presentation title: Understanding the Short- and Long-term Effects of the COVID-19 Pandemic on the Overdose Crisis

Opioid-related overdose increased sharply during the COVID-19 pandemic highlighting the need to understand the impact of Big Events on overdose and the types of policy measures that can prevent similar increases from future events. In this presentation, Dr. Cerdá will present the methods her team will use on a newly funded study to explore the COVID-19 pandemic and its effects on overdose and related outcomes; identify policy responses to COVID-19 that affected individual-level overdose risk; and examine how the pandemic’s impact on overdose risk varied across communities and populations.

Magdalena CerdaMagdalena Cerdá is a Professor and Director of the Center for Opioid Epidemiology and Policy, at the Department of Population Health at NYU Grossman School of Medicine. She obtained her doctorate from the Harvard University School of Public Health in 2006, and is a former Robert Wood Johnson Health and Society Scholar. Her research focuses on the effects that state and national drug and health policies have on substance abuse trends, and on the ways the urban context shapes violence. Current funded research focuses on the impact that cannabis laws and opioid policies have on substance abuse, mental illness, and associated health problems in the United States and South America. In addition, she is evaluating the impact that firearm disqualifications based on mental illness and substance abuse criteria could have on population-level rates of firearm-related mortality.

Location: Zoom
Presented by: Aria Crump, ScD
Presentation title: Practicing Resilience






Science is an exciting, challenging, and rewarding career choice, particularly when your work is in the service of human health. Despite this, early career scientists must master new skills, build reliable professional networks, and make pivotal career decisions, all while navigating personal lives and family obligations.  The stress of these challenges often taxes the mental well-being of scholars.  Dr. Crump will introduce the concept of resilience as a practice and discuss why it is so critical for junior investigators to know themselves and be their own best advocate.

CDUHR Symposium: Big Events: Approaches to Studying and Reinvigorating HIV Prevention and Care for People Who Use Drugs in the Midst of Societal Disruption – February 13, 2024 (Video)
Tuesday, February 13, 2024, 9:00 am-12:00 pm
Location: Zoom
Presented by: David Perlman, MD; Sam Friedman, PhD, Tetyana Vasylyeva, MSc, MPH, DPhil; Tim Rhodes, PhD
Presentation title: Big Events: Approaches to Studying and Reinvigorating HIV Prevention and Care for People Who Use Drugs in the Midst of Societal Disruption

Recent history has shown that gains in HIV elimination among people who use drugs are susceptible to erosion by large-scale, sudden onset “Big Events” that interrupt access to services and alter substance use networks, patterns, and practices. Environmental disasters, economic crises, wars and conflicts, and pandemics are examples of Big Events that have disrupted HIV, HCV, and substance use disorder (SUD) prevention and treatment, and sometimes lead new populations to use drugs. In this first of a series of symposia and other events, we will provide examples of how Big Events have changed the course of the HIV, HCV, and substance use epidemics and of how research on these changes has been conducted.

NYC DOHMH/DPA/CDUHR Quarterly Briefing – January 17, 2024
Wednesday, January 17, 2024, 4:30 pm-6:00 pm
Location: Zoom Webinar
Presented by: Ellenie Tuazon, MPH & Alex Harocopos, PhD MSc
Presentation title: New York City 2022 Overdose Mortality Data


Recent data from the New York City Department of Health and Mental Hygiene (DOHMH) demonstrates that the overdose epidemic continues to worsen in NYC, with older Black New Yorkers experiencing the highest rates of overdose in the city. New data indicating the setting of overdose show that approximately seven out of ten overdoses occurred in a private setting; however, overdoses in public outdoor settings have also increased in recent years.

NYC’s 2022 overdose mortality data will be presented and highlight responses implemented by the Health Department to help inform efforts to reduce overdose deaths, and discuss what more can be done to ensure that New Yorkers get the information and support they need to mitigate overdose risk.

CDUHR Seminar – Wiley Jenkins – January 9, 2024 (Video)
Tuesday, January 9, 2024, 10:30 am-11:30 am
Location: Zoom webinar
Presented by: Wiley Jenkins, PhD, MPH, FACE
Presentation title: Variation in HIV Risk Behaviors Among People Who Use Drugs in Rural US Communities








The opioid and drug use epidemic continues to evolve and expand. While the proportion of new HIV cases attributable to drug injection is increasing, it remains relatively modest in comparison to sexual transmission. Drawing data from the 8-site Rural Opioid Initiative which recruited rural people who use drugs (PWUD) across 10 states, we found significant variation in the frequency of drug use and sexual behaviors associated with infectious disease transmission and their association with participant characteristics such as age, race, and sexual orientation.
