Mike Fasullo higher resolution-2 (1).jpgMichael Fasullo, PhD

State University of New York Polytechnic Institute 

Dr. Michael Fasullo is an Associate Professor at State University of New York (SUNY) Polytechnic Institute and an adjunct professor in the School of Public Health, SUNY at Albany. He is also a member of the RNA Institute at SUNY Albany. He has more than 33 years of experience in the field of genetic toxicology and has been a member of EMGS for over 25 years.

Michael obtained his B.S. from Massachusetts Institute of Technology and a Ph.D. from Stanford University, where he investigated mechanisms of genome rearrangements using budding yeast strains specifically designed to measure unequal sister recombination, translocations, and gene conversion. These assays have been useful for designing similar assays in mammalian cells. He then conducted postdoctoral studies at Columbia University where he investigated the recombinogenic effects of radiation and chemical carcinogens. These studies were continued at the Stritch School of Medicine (Loyola University) before joining the Albany Medical College and SUNY Polytechnic Institute. A major emphasis of his work has been investigating mechanisms by which cell cycle checkpoints suppress radiation and carcinogen-associated genome instability.  To metabolically activate carcinogens, his recent work focused on expressing human cytochrome P450 (CYP) genes in budding yeast, and performing high throughput screens to identify genes that confer resistance to food carcinogens. These screens have identified novel genes that suppress aflatoxin-associated mutations. An interesting spinoff has led to methods to phenotype CYP polymorphisms using genotoxic endpoints in budding yeast. His research has been funded by governmental agencies, including National Cancer Institute, National Institute of Environmental Health Sciences, Department of Defense, and by private granting agencies, including the March of Dimes and Leukemia Research Foundation. He actively collaborated with a broad range of international scientists and has participated in interdisciplinary panels sponsored by the National Academy of Sciences Keck Futures Initiative, including The Genomic Revolution -- Implications for Treatment and Control of Infectious Disease (2006) and Nuclear Technologies (2013).

He continually advocates for research and pre- and postdoctoral training using model organisms as a reviewer on NIH, NSF and NASA review panels. He has mentored many undergraduates in the laboratory, who have further pursued careers in medicine, engineering, and biomedical science. His excellence in teaching genetic toxicology and biochemistry was recognized by the undergraduate student association for SUNY Polytechnic Institute in 2021.

Michael has attended and spoken at multiple EMGS meetings and credits his first successful NIH application to suggestions from EMGS members. He is a strong advocate for networking among faculty, researchers, trainees, and postdoctoral fellows. He currently participates in multiple SIGS, including DNA Repair and Genomics and Data science. He looks forward to attending and participating in the 2021 EMGS meeting.

2019 Headshot Clint Valentine.jpgClint Valentine, MSc

TwinStrand Biosciences

Clint Valentine is experienced in the fields of genomics, genetic toxicology, and analytical chemistry. Clint earned his early career training as a research assistant in the lab of Dr. John Essigmann within the Biological Engineering department of MIT. These experiences laid the foundation for Clint’s passionate interest in mutagenesis, the initiating events of carcinogenesis, and cancer progression. At MIT, Clint was one of the first to use the Transgenic Rodent (TGR) assay and Duplex Sequencing (an advanced form of error-corrected NGS) to study the mutagenic effects of the health-relevant environmental mycotoxin Aflatoxin B1 in an exposed murine transgenic model. Clint and his colleagues published results that revealed an induction of mutagenesis before phenotypic changes appeared mere weeks after mutagen exposure. The impact of this work has had a significant effect on the utility of using high-throughput genomics for mutational research, drug & chemical safety assessment, and cancer risk evaluation in humans.

After Clint’s experience at MIT, he transitioned from toxicology to computational biology and his goal evolved into commercially developing Duplex Sequencing into a regulated assay for genetic toxicology endpoints. Clint joined TwinStrand Biosciences as one of the earliest employees and simultaneously began studying bioinformatics through a Master of Bioinformatics program offered by Northeastern University, which he later earned in 2017.

During Clint’s tenure at TwinStrand Biosciences, he built a computational biology department. In 2019, Clint was promoted to direct the department, and he now leads over a dozen doctorate-level scientists and engineers who focus on building assays that apply to early cancer detection, cancer monitoring, forensics, and, importantly, genetic toxicology, among others.

In Clint’s current role as a Director of Computational Biology, he practices good scientific stewardship through the continued publication and presentation of peer-reviewed works, collaboration with industrial, academic and government groups, as well as volunteering with EMGS as a Special Interest Group co-chair, which he intends to increase commit towards.

Endowment Fund Chair Candidates

Miriam Poirier.jpgMiriam C. Poirier, PhD

National Cancer Institute- Retired 

Miriam C. Poirier Ph.D., who is currently a Scientist Emeritus at the National Cancer Institute (NCI), NIH, was Head of the Carcinogen-DNA Interactions Section (1997-2015) in the Laboratory of Cancer Biology and Genetics. She recognized internationally for pioneering the determination of DNA adducts and their sequelae in humans. Her studies have focused on the genotoxicity of carcinogenic polycyclic aromatic hydrocarbons (PAHs), as well as genotoxicity and mitochondrial toxicity of pharmaceuticals including cisplatin, tamoxifen and the antiretroviral nucleoside reverse transcriptase inhibitors (NRTIs) used for therapy of HIV-1. Dr. Poirier’s research, conducted with technicians, students, postdocs and collaborators, provided important insights into mechanisms of cancer causation in humans. She initiated the development of carcinogen-DNA adduct antisera, which were used to determine DNA adducts by immunoassay and immunohistochemistry in human tissues. Her studies showed a correlation between high levels of cisplatin-DNA adducts and favorable disease response in ovarian cancer patients. They also demonstrated incorporation of the NRTI zidovudine (AZT) into leukocyte DNA of infants born to HIV-1-infected mothers receiving NRTI therapy. Further studies showed DNA incorporation, mutagenesis, and tumor formation in mouse offspring exposed to AZT during gestation, suggesting that human infants exposed in utero may be at risk for cancer later in life. In primate offspring born to dams receiving human-equivalent doses of antiretroviral drugs during gestation, genotoxic changes were shown to persist in bone marrow stem cells at 3 yr of age (equivalent to a 15 yr old human). Dr. Poirier’s NRTI studies resulted in several alterations in public health policy, including changes in the Informed Consent for NIH-funded studies involving AZT, changes in the package insert for AZT, and changes in the CDC Guidelines for use of antiretroviral drugs in pregnant women infected with HIV-1. On the strength of these studies, Dr. Poirier was invited to chair a meeting of the International Agency for Research on Cancer that considered a potential human cancer risk of AZT. Late in her career Dr. Poirier pioneered the documentation of PAH-DNA adducts in beluga whale small intestine in a study linking high gastrointestinal cancer rates with PAH exposure in the beluga aquatic environment.  

Dr. Poirier is first or co-author of more than 275 publications and 400 abstracts, and has served in an advisory capacity on numerous US Government and non-Government committees. She received the Society of Toxicology (SOT) Women in Toxicology Service Recognition Award (2007), the NCI Leading Diversity Award (2012), and the NCI WSA Mentoring and Leadership Award (2014).  A previous Environmental Mutagenesis and Genomics Society (EMGS) Council member, Dr. Poirier also served as Chair of both the EMGS Molecular Epidemiology Special Interest Group and the EMGS Publications Policy Committee. She is a past President of the Society of Toxicology Carcinogenesis Specialty Section. In 2015 Dr. Poirier received the Genetic Toxicology Association (GTA) Excellence in Science Award and the EMGS Alexander Hollaender Award. Subsequently she served GTA as an Executive Board member, and EMGS as Program Chair in 2018, President in 2019, and Past President and Chair of the Nominating Committee in 2020.
