He has developed, transferred, and supported several commercial processes focused on monoclonal antibody purification. Dmitriy has a history of developing novel solutions related to continuous processing such as researching buffer systems that are suitable for continuous operations as well as multi-column chromatography.

Dr. Amit Dutta - Staff Scientist

Dr. Amit Dutta is a protein separations expert. He did his PhD with Prof. Georges Belfort at Rensselaer Polytechnic Institute, Troy, NY. His doctoral work was on rhelological properties of proteins and synthetic polymers at solid–liquid interfaces. Dr. Dutta joined ChromaTan in October 2013 as a postdoctoral fellow and has since become a full time member of the ChromaTan team. Dr. Dutta is deeply involved in laboratory work as well as modeling development and grant writing.

Dr. Soroosh Soltani – Cell Culture Engineer


Dr. Soltani joined ChromaTan in October 2015. He has since become a key member of our team and is responsible for planning and executing cell culture projects for the development of the Integrated Continuous and  Single-Use Bioproduction Platfrom (ICS). Dr Soltani has become an expert in running and optimizing perfusion bioreactor processes.   He received his Ph.D. degree in Chemical and Biomolecular Engineering from University of Akron. His research was focused on microbial fermentation for high-value bio-surfactant production from low-cost carbon sources. 

Jasmine Tan - Associate Engineer

Jasmine Tan joined ChromaTan as a full time associate engineer after receiving a B.S. in Chemical Engineering and a minor in Music Performance from The Pennsylvania State University in 2015. She primarily works on process development, characterization, and setup for CCTC processes as well as CCTC operation. Jasmine is also responsible for investigating next generation resin, device and sensor technologies with the objective of further enhancing CCTC system performance.

Bill Muzika - Controls Engineer


Bill joined ChromaTan in January 2016 as an intern while studying at the Pennsylvania State University. After graduating with a degree in Chemical Engineering and a minor in Biochemistry and Molecular Biology in May 2017, Bill joined the ChromaTan team on full-time basis primarily focusing on the development of the controls, hardware and software platforms for the CCTC systems. While a student, Bill worked in Dr. Wayne Curtis’s lab studying the growth of autotrophic bacteria for biofuels as well as enabling scaled down testing of bacteria in hazardous atmospheres.

Jonathan Walko - Associate Engineer


Jonathan joined ChromaTan after receiving a B.S. in Chemical Engineering from Penn State University in December of 2016. As an undergraduate, Jonathan worked in Dr. Andrew Zydney's lab studying the behavior of a fusion protein during ultrafiltration. As an Associate Engineer at ChromaTan, Jonathan performs CCTC characterization, setup, operation, data analysis and modeling.
