CDD Leadership
Executive Team


Barry Bunin, Ph.D.
CEO and Board Director
Barry A. Bunin, Ph.D. is the CEO of Collaborative Drug Discovery. Dr. Bunin has overseen $50 million in business transactions over the last two decades. Prior to CDD, he was an Entrepreneur in Residence with Eli Lilly & Co. Dr. Bunin is on a patent for Kyprolis™ (Carfilzomib for Injection) — a selective proteasome inhibitor that received accelerated FDA approval for the treatment of patients with multiple myeloma that was widely viewed as the centerpiece of Amgen’s $10.4 Billion acquisition of Onyx Pharmaceuticals.
Dr. Bunin was the founding CEO, President, & CSO of Libraria (now Eidogen-Sertanty). At Libraria, he led a team that integrated exhaustive reaction capture (synthetic chemistry) with gene-family wide SAR capture (medicinal chemistry). On the scientific side, he co-authored “Chemoinformatics: Theory, Practice, and Products” (Springer-Verlag), a text that overviews modern chemoinformatics technologies, and “The Combinatorial Index” (Academic Press), a widely used text on high-throughput chemical synthesis.
In the lab, Dr. Bunin did medicinal synthetic chemistry developing patented new chemotypes for protease inhibition at Axys Pharmaceuticals (now Celera) and RGD mimics to inhibit GP-IIbIIIa at Genentech. Dr. Bunin received his B.A. from Columbia University and his Ph.D. from UC Berkeley, where he synthesized and tested the initial 1,4-benzodiazepine libraries with Professor Jonathan Ellman.

Sylvia Ernst, Ph.D.
Sr. Manager, Commercial Operations
Sylvia Ernst, Ph.D. is the Head of Sales and Sales Operations at Collaborative Drug Discovery, Inc. Dr. Ernst received her Ph.D. in Chemistry in Frankfurt, Germany working in the group of Prof. Dr. Wolfgang Kaim. At that time her research focused on using computational chemistry to find new catalysts for exploiting energy from sunlight.
She has over 20 scientific publications. Interested in chemical information and technology, she joined the Beilstein Institute and was a member of the core team which launched “CrossFire Beilstein”, a database which today is known and used by almost every chemist in the world. From there Sylvia worked in customer-related functions with Beilstein Information Systems, MDL Information Systems, Elsevier MDL, and SciTegic/Accelrys. She joined CDD in 2007.
Sylvia's extensive work with many pharmaceutical and biotech companies as well as academic and government institutions spans the globe, giving her a unique perspective on how the drug discovery and development process is evolving, and how new approaches may impact world health. She joined CDD because she believes that the best response to emerging global health crises is to foster collaborations that join the world's enormous research capabilities into unified efforts.


Kellan Gregory
Director of Product Excellence
Kellan Gregory is CDD's Director of Product Excellence. He has a degree in Chemical Engineering with an emphasis in biotechnology from Tufts University. Kellan was co-author in an HIV study with Dr. Paul A. Volberding, and interned with BioRad and Libraria.
He has not written two books and founded two companies like Barry Bunin, PhD. Unlike Sylvia Ernst, PhD, he did not help with commercial introductions of both Beilstein and Pipeline Pilot. And he’s at least 99 articles and 3 books behind Sean Ekins, Ph.D., who has experience working with two big Pharmas.
But you know what? If you want a product expert with the most experience using data and databases, the strongest people skills and the ability to tell you straight up what will and will not work, Kellan Gregory – with his growing team of specialists in the product group – is your best collaborator. Kellan also creates practical specifications for our product enhancements by prioritizing thousands of requests from hundreds of CDD customers.

Alex Clark, Ph.D.
Research Scientist
Alex Clark has been building cheminformatics and computational drug discovery software products since the early 2000's, after spending a decade learning to be a scientist the hard way: running reactions at the lab bench.
Since switching to informatics full time, he has worked on most areas of contemporary chemistry software, whether it be 2D or 3D, large scale (cheminformatics) or small scale (quantum chemistry), big molecules (proteins) or small molecules (drugs). He has a persistent interest in the interface between scientists and software, which continues to challenge our industry, and has done much work on visualization techniques, electronic lab notebooks, and reimagining traditional software for new platforms like mobile, cloud and web.
He publishes regularly in the scientific literature, and has maintained a large number of collaborations since becoming an entrepreneur in 2010. Whenever he is not working on projects for CDD, he continues to maintain his own company, Molecular Materials Informatics, relentlessly experimenting with all manner of future-oriented chemistry software ideas, methods and products. Alex completed his doctorate at the University of Auckland, New Zealand, in 1999, and subsequently relocated to North America.
