As Founder and Director, Erik focuses on overall leadership of DiscoveryBioMed, Inc. As CSO, he serves as the principal science consultant in client work and in managing the company’s research and development. He brings several years of experience as a researcher in cell physiology and pathophysiology. He has focused on receptors and ion channels in human epithelial cells that regulate ion transport and that are pertinent to therapeutics for cystic fibrosis, polycystic kidney disease, and diabetes mellitus. He currently focuses his scientific efforts as an applied discovery scientist, applying his cell physiology and pathophysiology training to DBM programs. He was previously an Associate Professor with tenure at the University of Alabama at Birmingham. Prior to that, Erik was a postdoctoral fellow at the Johns Hopkins University School of Medicine. His education includes a Ph.D. in Physiology from Dartmouth College and a B.A. in Biology from Grinnell College. Erik is originally from Princeton, NJ.


John H. Streiff, Ph.D., Chief Chemoinformatics Officer

As Chief Chemoinformatics Officer, John serves as the company’s specialist in pharmacology, molecular structure modeling, pharmacophore analysis, life science modeling, bioinformatics and cheminformatics. Not only is Dr. Streiff adept at finding ‘commonality in structure’ among DBM’s validated hit compounds but he is also facile at conversion of HTS bioassays into automated and robotic formats. His previous experience includes research on molecular pharmacology of anesthetic drugs at the University of Alabama at Birmingham and at Mayo Clinic where John was an Assistant Professor. Dr. Streiff’s education includes a B.S. in Chemistry from the University of Northern Iowa and a Ph.D. in Chemistry from the University of Idaho. John is originally from Rochester. MN


Deborah Mai, Ph.D., Chief Biological Officer

As principal scientist, Deborah engages in both internal R&D and on-going service contract programs at DBM.  She received her Ph.D. and postdoctoral training under Dr. Adrie Steyn at the University of Alabama at Birmingham, where she studied Mycobacterium tuberculosis and developed a novel HTS system to identify small molecule inhibitors of protein-protein interactions in mycobacterial cells.  Dr. Mai utilizes her training to develop, optimize, and perform cell-based drug screening platforms at DBM.  Her expertise and knowledge in bacterial pathogenesis enables DBM to expand in its R&D and drug discovery services to include anti-infective programs.  Deborah received her BS in Microbiology from Auburn University.  She is originally from Tuscaloosa, AL.

He is very adept at bioassay design and optimization. Eric is originally from Montgomery, AL. The Chief Laboratory Officer position was eliminated in order to pursue a re-structuring of the company.

Dr. Joseph P. Ritchie was Head of Business Development and a Staff Scientist from early 2011 through early 2014. While at DBM, Joe was DBM’s point person for business development and also performed ‘hands on’ science in DBM laboratories. He was facile at organizing DBM’s efforts at the BIO meetings and in establishing a Rolodex of contacts within BioPharma for our R&D programs for future partnership and for CRO services client business. Joe is originally from the Birmingham, AL area. He received his Ph.D. in 2010 from UAB in oncology therapeutics development. He is currently a medical science liaison in oncology with Bristol-Myers Squibb.

Dr. Thomas H. Barr was Chief Operations Officer from the company’s inception and launch in H2 2007 to 2010. While at DBM, Tom was essential in establishing the business operations and financial infrastructure as well as helping equip the laboratories at DBM. During his time at DBM, he garnered an MBA from the UAB School of Business. Through his new venture, Entreventures Consulting, Tom helps start-ups and entrepreneurs in entrepreneurial and educational endeavors. When not pursuing this effort, Tom also teaches mathematics, statistics, financials and entrepreneurship at Indian Springs School and at the UAB School of Business.

Dr. Terry Porter, Ph.D. was a key strategic business consultant for DBM at a critical time in our growth between 2009 and 2011 between stints with worldwide business development teams at GlaxoSmithKline and with his now active effort with Takeda.

All past and current DBM principals, whether full-time or part-time, added significant and appreciated value to DBM, Inc. or continue to do so vigorously.

DiscoveryBioMed, Inc. (DBM) is a life sciences and biotechnology company, located in Birmingham, AL, formed with the ultimate goal of integrating human cell physiology with the drug discovery critical path. DBM’s founder, Erik Schwiebert, Ph.D., a physiologist by trade, launched the company in October 2007 and closed on seed capital investment with Greer Capital Advisors in November of 2007 (Birmingham Technology Fund). Since then DBM has continued to grow and gain recognition both locally and nationally.

DiscoveryBioMed’s mission is to fill a critical niche within the drug discovery industry by specializing in custom human cell engineering and human cell-based drug discovery. Our R&D infrastructure and know-how are leveraged as a CRO service to support the commercial and academic drug discovery community by integrating human cell platforms at any and all points within the drug discovery critical path, from HTS assay development and optimization to lead prioritization and progression, with the end product being ‘high value’ clinical candidates.

Academic labs and small biotechs have been adopters of our human cell platforms early in the drug discovery process, whereas large BioPharmas have been more interested in DBM’s capacity to design, develop and implement primary human cell systems for lead prioritization and progression. As an example of our services, DBM routinely performs targeted and phenotypic HTS assay development and primary HTS, custom primary cell culture and/or immortal cell line creation and secondary/tertiary validation and mechanism of action analysis with primary human cell systems.

DBM refers to our novel scientific approach and niche within this marketplace as Humanized Drug Discovery.

If the end goal is to give a drug to a human patient, why not discover new drugs with relevant human cell platforms? The DBM approach to drug discovery is designed to improve the attrition rate and yield high value clinical candidates by introducing disease relevant and physiologically relevant human cell platforms as early as possible in the drug discovery process.


Discovery BioMed’s scientific expertise has developed over many years of human cell physiology research.

Our laboratory is equipped with a state-of-the-art cell culture and engineering facility. Coupled to that, we have high-throughput molecular screening (HTS) capability with all types of luminescence, fluorescence, and absorbance detection. These facilities provide the means to perform many different high-throughput bioassays on human and mammalian cell-based platforms.

Our compound libraries come from diverse synthetic and natural-product sources. The selection of these libraries is guided by our company’s expertise in physiology and biochemistry. DBM has more than 75,000 small molecules as well as phytochemical extracts available to test on each endpoint, target, pathway or system.

DBM’s philosophy is that the best molecular screening approach to drug discovery is to utilize in vitro cell lines or primary cultures (preferably, human) that are as close to in vivo conditions as possible. Its diseased and wild-type cell lines are engineered to retain phenotypes through many cycles of cell division, leading to reliable results from cell screening assays. DBM refers to this innovative approach as Humanized Drug Discovery.

In its own discovery work using the same infrastructure as its services business, DBM brings the same expertise, tools, and philosophy to bear on identifying compounds with promise as therapeutics for respiratory, metabolic, and hyperproliferative (renal, urologic, oncologic) human diseases.
