Helping biopharmaceutical companies turn
data into better medicines

Plex Research was founded on the notion that more data should mean better medicines.  To accomplish that goal, we’re making the world’s scientific data findable, accessible, searchable, and transparent from a single location.

Douglas Selinger

Chief Executive Officer & Founder

As an early pioneer of microarray technology, Doug authored some of the first publications describing experimental and computational approaches for large scale transcriptional analyses. After completing his Ph.D. in George Church’s lab at Harvard, he joined the Novartis Institutes for Biomedical Research where his 14-year career spanned the entire drug discovery pipeline, including significant work in target ID/validation, high throughput screening, and preclinical safety.

In 2017, Doug founded Plex Research to develop a novel form of AI based on search engine algorithms. Plex’s unique platform has helped dozens of biotech and pharma companies accelerate their drug discovery pipelines by providing interpretable and actionable analyses of massive chemical biology and omics data sets.

Timothy Wall

Chief Architect
Tim has over 20 years of computing and cloud security expertise.  In his most recent role as the Chief Architect of CloudLock, Tim was responsible for building a scalable cloud security platform, and creating policy-driven responses to cloud application activity, through APIs and other forms of connectivity.  CloudLock was acquired by Cisco for $300M in 2016.  Tim has a Sc.B. in Electrical Engineering and Computer Science from MIT, and an Masters in Engineering from Brown University.

Jed Gaetz

Principal Scientist
Prior to joining Plex Research, Jed worked in R&D at Sema4 (now GeneDX). As part of their Cancer and Pharma Knowledgebase team, Jed contributed to precision oncology reporting and clinical trial matching for thousands of patients and studied real world evidence for rare diseases. Jed received his PhD from Rockefeller University in cell biology under the mentorship of Tarun Kapoor, and then went on to complete a postdoc in the Dept. of Human Genetics at the University of Chicago.

Ehab Khalil

Principal Scientist
Ehab is a seasoned medicinal chemist with over 14 years of experience in drug discovery from several biopharmaceutical companies, including 3-Dimensional Pharmaceuticals, Johnson & Johnson, and Celgene. His contributions to lead discovery and optimization have resulted in several clinical candidates in oncology (kinase inhibitors, IMiDs, and Cereblon-based molecular glues) and antimicrobials. While at Celgene, he also joined the process chemistry team, contributing to synthesis optimization and scale-up of various development candidates. Since joining Plex Research, he has worked closely with the team to fully leverage the Plex platform, helping clients address challenging questions related to phenotypic screens, target deconvolution, and off-target activity determination. Ehab completed his Ph.D. at the University of Minnesota, a postdoctoral fellowship in bioorganic chemistry at the Rockefeller University, and a B.S. in Pharmacy at St. John’s University.

Eleni Stylianou

Principal Scientist
Eleni is a molecular cell biologist with more than two decades of independent biomedical research experience. She was a Principal Investigator/ Assistant Professor at the Lerner Research Institute, Cleveland Clinic and before that a tenured Lecturer at the University of Nottingham Medical School (U.K.). She successfully led research teams focusing on inflammatory gene regulation and epigenetics in complex diseases. After leaving academia, she founded her own consulting business and has worked with cross-disciplinary teams from pharmaceutical companies and biotech firms. At Plex, her focus is on translating AI-driven analyses into actionable strategies to expedite drug discovery. She is a graduate of the University of London and completed her Ph.D. at the University of Wales, UK.

Oren Levy

Biology Consultant

Oren is a cell biologist and bioengineer. Prior to joining Plex as a biology consultant, Oren spent 3 years as Vice President of R&D for one of the largest privately held, multi-state medical cannabis companies in the U.S., leading discovery, advancement, and commercialization of proprietary cannabis-based therapies for regulated markets. Prior to that, he worked at the Wyss Institute at Harvard Medical School, leveraging Organ-on-Chip systems for human disease modeling and drug discovery. Earlier in his career, he served at a junior faculty position as an Instructor of Medicine at Harvard Medical School and an Associate Bioengineer at Brigham and Women’s Hospital. His biomedical engineering research was focused on development of engineered cell-based platforms and novel drug delivery systems towards discovery of cutting-edge therapies for the treatment of devastating diseases, including autoimmune, neuro-degenerative diseases and cancer.
