Libby continues to work with the university as a lecturer in the Chemical Engineering department.


Senior VP of Quality

Joanne Izyk will lead the Quality Management team at Neva Analytical, Inc. with over 23 years of pharmaceutical, horticultural and science education experience. Immediately prior to joining Neva, Joanne was the Director of Quality Assurance at Correvio LLC (a Cardiome company) where she was responsible for a variety of global Quality Management Systems (QMS) activities. These responsibilities included the management and execution of the quality and compliance audit program for affiliates, partners and contractors in over a dozen different countries on a worldwide basis. Joanne also brings to Neva hands-on experience from both commercial and development-stage pharmaceutical companies in the areas of quality control (including HPLC and various wet chemistry & physical testing techniques), analytical research and stability, technical report writing, Laboratory Information Management systems, as well as the unique compliance and regulatory expectations covered by Titles 21 of the US Code of Federal Regulations, ICH, EMA, and Health Canada. With her varied global background, Joanne will serve Neva and its clients with excellent attention to detail, comprehensive global quality, compliance and technology perspectives — and an overall commitment to execute timeline driven objectives.

Ashley Kosz


Prior to joining Neva’s team, Ashley spent over two years in the contract research industry as an Associate Scientist. In this role, she was responsible for running a variety of analyses on large molecular weight, biologically active compounds to determine individual physical properties and quantifying related analytes within the drug substance or drug product.

These analyses were all performed while strictly adhering to cGMP protocols and included HPLC, capillary isoelectric focusing, capillary electrophoresis, gel electrophoresis, UV-spectrophotometry, and coagulation assays.

In addition, she was responsible for executing stability studies and regularly performed release activities for commercial stage drug products. She has also been thoroughly involved with method verifications, bridging studies, and analytical method transfers.

Preceding her involvement in the pharmaceutical industry, she was employed as a QA Regulatory Technician for a GMP food flavor manufacturer where she was responsible for writing technical documentation for commercial products.

Furthermore, Ashley spent two years working as an undergraduate analytical chemistry research assistant studying nutrient density profiles of Lake Michigan before graduating with a B.S. in Biology with a minor in Chemistry from University of Wisconsin-Milwaukee.

Jennifer Hanson

QM/QC Associate
