Scientific Advisory Board

Michael Böttcher received his diploma in biology at the University of Hamburg in 1987. He obtained his PhD in 2004 at University Duisburg/Essen for lymphocyte micro-chimerism studies after liver transplantation. Since 1988 he is working in private labs with special focus on TDM, drugs of abuse, and alcohol biomarkers. Michael Böttcher is the head of toxicology department of MVZ Labor Dessau Kassel GmbH (Limbach Gruppe) which is one of the biggest drug testing labs today in Germany. The department is working in all kinds of drug and alcohol testing eg.: occupational health and traffic medicine, clinical drug screening, addiction medicine, therapeutic drug monitoring etc. They are also performing confirmation and specialized analysis in different body fluids for other labs and forensic institutes in Germany and Europe. 

Judy Hahn is a Professor of Medicine in the HIV, ID, and Global Medicine Division in the Department of Medicine at the University of California, San Francisco. She is an epidemiologist with extensive experience studying the behavioral and biological intersections of substance use and infectious diseases. She leads multiple National Institutes of Health (NIH)-funded studies to reduce the harmful impact of alcohol use on HIV outcomes, primarily in east Africa. She was among the first HIV/alcohol researchers to use phosphatidylethanol (PEth) in her research, as well as other biomarkers, for objective measurement for alcohol use in observational and intervention research. She has authored or co-authored over 130 manuscripts, with more than 20 using PEth to objectively measure alcohol use. She is the Principal Investigator of multi-site studies of providing therapy to prevent tuberculosis (TB) disease among persons living with HIV who engage in heavy alcohol use in East Africa (Uganda), as well as randomized controlled trials (RCT) to examine the efficacy of behavioral interventions to reduce alcohol consumption in this population. These studies employ both PEth and urine ethylglucuronide (uEtG) as measures of alcohol use. She also has experience using transdermal sensors of alcohol use. Dr. Hahn is a committed teacher and mentor, directs courses on grant-writing, and conducts one-on-one mentoring of scholars at all levels of academia, and looks forward to developing new collaborations via PEth-NET.

Martin Javors, PhD, RPh, obtained a degree and license in Pharmacy in 1967 (UT-Austin), practiced pharmacy for several years, PhD (Pharmacology, U Colorado-Boulder) in 1979, and post-doc in Pharmacology in 1982 (UTHSC-San Antonio). His current position is professor in the Department of Psychiatry at the UTHSC-SA and director of the Biological Psychiatry Analytical Labs (BPAL), a clinical and research lab that he founded in 1984. Dr. Javors is part of a research group at UTHSC-SA that studies the combination of biomarkers of alcohol consumption that includes BAC, breath alcohol (observed via video), transdermal alcohol, CDT, EtG, and phosphatidylethanol.

Dr. Javors has studied biomarkers/metabolites of several drugs of abuse for the past 20 years. His more recent, primary interest, grants, and publications have focused on development and interpretation of biomarker measurements to identify/quantify recent alcohol consumption for clinical treatment studies, general medical practice, and forensic applications. Current basic research projects involve the characterization of the pharmacokinetics of PEth homolog synthesis and elimination as well as the characterization/interpretation of the variability of the alcohol consumption/PEth relationship among humans. The overall goal of this research is to improve the accuracy of PEth homolog measurements to estimate the timeframe, quantify, and pattern of recent alcohol consumption.
