Scientific Team



Keith began his career by working in the formulations department at Dow Agrosciences. This was where a love for chemistry began, as he graduated with a degree in Biology, and where he developed and honed his laboratory skills. In January, 2012 he started working with Cogent in the normal phase chromatography flash lab. With his hard-work ethic and ability to learn new processes quickly, he set himself apart and became well trusted by Cogent clients.

After working in the flash lab for nearly a year, he was given the opportunity to move to the open-access lab where he excelled doing HPLC and reversed phase flash purifications. His leadership and mentoring skills were rewarded with a promotion to team leader in February of 2014.

Keith has learned many purification techniques and has excelled at being efficient in each technique. He has expert knowledge in normal phase and reversed phase flash chromatography. He has been creative and innovative, which has allowed him to excel running HPLC purifications and large scale normal phase method development. He has shown his ability to learn quickly in the chiral lab where he mastered two purifications instruments. Keith has also processed samples for the APL lab. This required him to learn how to use a couple of automated liquid handlers, which he picked up very quickly in a time of need. He has shown the desire to grow and become a large contributor in several different areas. With his ability to master several types of purification techniques, he is able to train and assist several labs to account for changing work flows.

Keith graduated from Indiana University in 2008 with a B.A. in Biology. In 7 years in the professional industry, he has gained valuable experience as a chemist and has become a very large asset to Cogent Professionals


Stephanie Bartlett is currently serving as the Analytical Chemist IV, Team Leader for the Chiral Purification group and has been since June 2014. Stephanie initially began her career as a contract chemist with VMC working on site at Eli Lilly and Company in the fully integrated remote access Automated Synthesis Lab. During her employment with VMC, her work ethic and skills were noticed by Cogent and offered a position. Stephanie joined Cogent in November 2011 as an Analytical Chemist working with the Physical Properties group in the Solubility and Stability lab. She joined the Chiral Purification lab in July 2012. Stephanie has excelled in all areas she has worked in largely due to her willingness to both learn from and help her peers and colleagues.

During her employment with Cogent Professionals, Stephanie has gained valuable knowledge and experience working with both the Solubility and Stability and the Chiral Purification Groups, furthering her proficiencies in sample preparation, method development, trouble shooting, LCMS, HPLC, and SFC. Her combined education and professional experiences have helped develop Stephanie into a top notch chemist with the ability to adapt to the situation while producing results.

Stephanie was born and raised in Anderson, Indiana. She graduated from Anderson University with a Bachelor of Arts in Biochemistry in 2009. She was immediately selected by her professors for an accelerated Masters of Business Administration program with Anderson University and graduated in 2010.


Kate began her career as a chemist in the in-process quality control testing group at Cook Pharmaceuticals after graduating with a Bachelor of Science in Chemistry from Indiana University.  There she set herself apart by her strong initiative to become proficient in a wide variety of analytical techniques and instrumentation, including UV/Vis, FTIR, GC, Karl Fischer Coulometers, Osmometers, Headspace Analyzers, Particle Counters, Endotoxin Readers, TOC Analyzers, with an emphasis on reversed phase and ion exchange HPLC. She quickly become an important contact in the laboratory for the drug formulation team to turn to for quick and efficient testing as well as troubleshooting and investigating out of specification results.

Kate eventually joined the technical service team and was responsible for writing several batch record templates for pharmaceutical manufacturing by working closely with clients and other departments. She also carried out extensive investigations into processing failures and recommended corrective action when necessary.

After realizing she was happiest in the laboratory, Kate took a position with the finished process quality control group.  There she enjoyed a wide variety of responsibilities in addition to routine testing, including working in conjunction with the research and development group in the improvement and validation of HPLC assays; writing, reviewing and revising standard operating procedures (SOP’s) used in the laboratory for specific pharmaceutical analysis as well as for instrument operation.  She was a member of a documentation team to develop a new worksheet based documentation system with a focus on easing LIMS integration. Because of her former experience in the technical services group, she was a primary resource for the review of batch records, both executed and templates, when pertaining to in-process and finished product testing. She was also responsible for writing and reviewing exception reports generated in the laboratory, and provided guidance to other analysts in writing exception reports.

After purchasing and relocating to a small hobby farm just north of Lebanon, Indiana, Kate began employment with Cogent in 2010 working in the Quantitative Biology group primarily doing LC/MS/MS. There she has continued to increase her skill set and knowledge base.  She has shown herself to be a valuable asset to the lab and takes pride in performing tasks, whether big or small, thoroughly, correctly, and with great enthusiasm.
