Who we are


Dr. Joseph Loscalzo

Dr. Loscalzo is the Hersey Professor of the Theory and Practice of Medicine at Harvard Medical School, Chairman of the Department of Medicine, and Physician-in-Chief at Brigham and Women’s Hospital. He holds two honorary degrees, has authored or co-authored more than 500 scientific publications, and holds 27 patents for his work in the field of medicine. Dr. Loscalzo received his A.B. degree, Ph.D. in biochemistry, and M.D. from the University of Pennsylvania. 

Accolades: George W. Thorn Award for Excellence in Teaching at Brigham and Women’s Hospital; Educator of the Year Award in Clinical Medicine from Boston University; The Glaxo Research Award; Election to the American Society for Clinical Investigation, the Association of American Physicians, and the Institute of Medicine of the National Academy of Sciences.

Dr. Albert-László Barabási

Dr. Albert-Laszlo is The Robert Gray Dodge Professor of Network Science and a Distinguished University Professor at Northeastern University. There, he directs the Center for Complex Network Research and holds appointments in the Department of Medicine at Harvard Medical School and Brigham and Women Hospital. He is also a member of the Center for Cancer Systems Biology at Dana Farber Cancer Institute. He received his MSc degree in Theoretical Physics at the Eötvös University and was awarded a Ph.D. three years later at Boston University.

Accolades: Dr. Albert-Laszlo is the author of NPR-acclaimed “Bursts” and many other influential works, including his most recent: “Network Science.” His work led to the discovery of scale-free networks in 1999, and proposed the Barabási-Albert model to explain their widespread emergence phenomenon in fields ranging from medicine to the Internet.

The Leadership Team

Alif Saleh, Chief Executive Officer

A global business leader and entrepreneur at heart, Alif draws from his scientific background in systems biology, network theory, and engineering at Scipher. Alif has successfully led cross-disciplinary teams in technology and business across Asia, Europe and the Americas - raising over $225 million in venture and private equity capital.  Previously with BCI (acquired 2000), Alfa Laval (IPO 2002), and Myriant (acquired 2014), Alif received his MSc degree in Chemical and Genetic Engineering from Lund Institute of Technology, Sweden.

Dr. Keith Johnson, Chief Scientific Officer

As co-chair of the Chromosome-19 Committee of the Human Genome Project, Keith is a well-known leader in the field of human genetics. He has built and led genetic labs for pharmaceutical companies in the U.S. and Europe, and was Executive Director at Novartis and Senior Director of Global R&D at Pfizer. Previously the Professor of Genetics at University of Glasgow, Keith received his PhD in molecular biology at the Imperial College London.

Dr. Dina Ghiassian, Director of Systems Biology and Network Medicine

Working with Dr. Albert-Laszlo Barabasi and Dr. Joseph Loscalzo, Dina has led the work of applying network science in medicine, and developed a suite of tools that are used by scientists and engineers across the world to improve the understanding of patient drug response.

Dina continues to explore the frontier of what predictive classifiers can achieve in medicine using her and Scipher’s unique multidiscipline approach including physics, biology, and medicine. She received her PhD in Physics from Northeastern University’s Center for Complex Network Research.


Sophie Chapelle, Chief Commercial Officer

During her 20+ year career in the pharmaceutical industry in business development and global sales and marketing leadership roles at UCB and Pfizer, Sophie also successfully built commercial operations for technology-based, personalized medicine growth companies such as Variagenics and CogState. Sophie received her MSc degree in Chemical and Biotechnology Engineering from University of Brussels (Belgium), Medicinal Chemistry from University of Lille (France), and her certificate of Business Excellence from the Columbia Management Institute in NY.



Dr. Nancy Schoenbrunner, Head of Diagnostic Development

Nancy joins from Roche Molecular Systems where she was Research Director with a proven track record in the medical device, in vitro diagnostic (IVD) and companion diagnostic fields. She headed up the Chemistry and Innovation Technologies department, interfaced closely with the CTO and Business Development and was responsible for the early phase R&D of several portfolios within Roche. Nancy received her Ph. D. in Biophysical Chemistry from the University of Basel.



Asher Ameli, Data Scientist

Asher is a Ph.D. candidate in physics at Northeastern University. He has previously worked at the Center for Interdisciplinary Research on Complex Systems at Northeastern University to visualize the robust yet fragile nature of the signaling networks. He has also worked at Channing Division of Network Medicine, Department of Medicine at Brigham and Women’s Hospital on a variety of collaborative projects on complex systems including the integration of multi-omics networks, disease-disease relationship and link prediction approaches. Asher is developing some versatile approaches via graph mining and neural networks to extract the latent features of the biological data.
