Dmitriy Fedorenko – Associate Director of Process Sciences


Dmitriy joined the ChromaTan team as a development engineer in 2016. In 2017 he was promoted to group leader of the laboratory group. Dmitriy’s group is responsible for executing experiments on all customer related and system related projects as well as next generation technologies. Prior to ChromaTan Dmitriy gained 5 years of experience in downstream processing at Abbvie. 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.

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.

Eben Crawford - Associate Engineer II


Eben graduated from the University of Massachusetts Dartmouth with an undergraduate degree in Bioengineering and is currently continuing his education working towards a MicroMasters in Data Science through MIT. He worked in fed batch mAb manufacturing for 2 years primarily in Downstream and assisting with activity in Upstream. Eben also has 2 years of experience in Downstream and Viral Clearance process development for mAb purification for over a dozen projects. To increase productivity, he developed a software suite using VBA and MS Excel to collect, filter, and scale data from PD to simulate expected manufacturing conditions to find cost savings and identify bottlenecks. Eben joined ChromaTan in October 2018 and is supporting CCTC process development, integration, and modeling activities.


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 PhD 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. 

April Hile - Operations Assistant


April Hile joined ChromaTan in January 2018 as an Operations Assistant. She dual functions in supporting the laboratory in upstream operations, as well as research compliance (e.g. - bookeeping, proposal preparation). April’s prior experience stems from her tenure in Penn State biochemical engineering & agricultural biotechnology lab (CurtisLab). Her contributions there included experimental demonstrations of low-cost bioreactor systems and support of over a dozen grant proposals including effort that directly resulted in the award of a $7M DARPA Insect Allies project.

Brad Olson - Mechanical Engineer I


Brad graduated with his master’s degree in Mechanical Engineering from University of Massachusetts Lowell on 2013, after which he began his PhD research in fluid structure interactions for mitigation of vortex induced vibrations. In December of 2018 he started working for ChromaTan while finishing his PhD. He specialties include fluid dynamics, composite materials and mechanical characterization of materials.
