Upcoming Seminars

The field of Forensic Science faces continual challenges and responds by developing new investigative techniques. Our Forensic Science Program at Loyola University Chicago strives to meet this rapidly changing environment by educating our students in innovative ways. To this end, we present our Forensic Experts Seminar Series featuring professionals who will present their work on current topics, ranging from DNA and drug analysis to the investigation of digital evidence.

We enthusiastically invite interested students, faculty and staff to join us for these events.

Topic: "DEA's Regulatory Response to the Evolving New Psychoactive Substance Market"

Dr. Van Linn will be discussing the trends and challenges of new psychoactive substances (NPS) on the illicit drug market and their impact on public health and safety and the regulatory response to protect the public.   Recent case studies and the scheduling process under the United States Controlled Substances Act will also be discussed.

Dr. Van Linn is a Drug Science Specialist in the Diversion Control Division, Drug Enforcement Administration (DEA). His professional responsibilities include collecting and evaluating data on newly emergent psychoactive substances and other substances of misuse and abuse.  Dr. Van Linn’s analysis and recommendations inform policy decisions and routinely Dr. Van Linn is called upon to provide expert testimony in Federal court.  Dr. Van Linn is actively monitoring the introduction of NPS with a special emphasis on synthetic opioids such as fentanyl analogues.  He routinely collects information from public health and law enforcement officials to evaluate these substances for possible control under the United States Controlled Substances Act (CSA), if warranted.  Also, in his scientific advisory capacity, Dr. Van Linn provides technical support and training to special agents, investigators, forensic scientists, and senior management on drug misuse and chemical diversion issues and provides guidance to industry regarding compliance with regulatory requirements.

Prior to employment in the Diversion Control Division at DEA headquarters, Dr. Van Linn was employed by DEA at the North Central Laboratory (Chicago, IL) as a Forensic Chemist.  Preceding employment in the Federal government, he was employed at Cambridge Major Laboratories (now Alcami Corporation) as a research scientist where he developed robust synthetic pathways for pharmaceutical ingredient manufacturing.  Dr. Van Linn conducted post-doctoral research at Drexel University College of Medicine in Philadelphia, Pennsylvania, holds a Ph.D. in Organic Chemistry (2009) from the University of Wisconsin-Milwaukee, and a B.S. in Chemistry and Biology (2004) from the University of Wisconsin-Stevens Point.

Deborah Zvosec, Ph.D.

Research Associate - Hennepin County Medical Center and Minneapolis Medical Research Foundation—Minneapolis, MN

Topic: "Drug-facilitated Sexual Assault:  A Case-based Presentation of Clinical, Toxicological and Legal Perspectives"


Dr.  Zvosec has conducted clinical research on health effects of gamma hydroxybutyrate (GHB) and its analogs since 1999, including toxicity, lethality, addiction and withdrawal, GHB-intoxicated driving, and GHB-facilitated sexual assault.  She has provided expert testimony on clinical effects of GHB/analogs in federal and state cases, hearings and grand jury proceedings and has consulted on a wide variety of drug-facilitated sexual assault cases involving GHB/analogs, benzodiazepines, and alcohol.  Dr. Zvosec obtained her M.S. and Ph.D. in Medical Anthropology, conducting bio-behavioral research on infectious diseases.  Subsequent focus on health impacts of GHB/analogs led to integrative research with Emergency Medicine physicians, toxicologists, and Medical Examiners.  She has presented research and lectured in the US and Europe to diverse medical professionals in fields of Emergency Medicine, Addiction Medicine, Internal Medicine, Psychiatry, Pediatrics, Clinical Toxicology, and to medical and legal professionals in fields of Forensic Toxicology, Forensic Pathology, and law enforcement. Dr. Zvosec currently works with the Department of Emergency Medicine at Hennepin County Medical Center, in Minneapolis, Minnesota, where she conducts and coordinates research projects on GHB/analogs, DFSA, and other clinical topics.  

Date & Time: March 30th, at 5:15 p.m.
