Mysore Ramprasad (Ram)

I have had the opportunity to work with, recruit, and hire Gio in the last 3 jobs (Halozyme, CovX, and Favrille). Gio is a bundle of energy and a must have in the lab. His strengths include his integrity and enthusiasm to work; being organized; flexibility to adapt to changes quickly and always available to help out with collaborations and having the sense of urgency to meet deadlines. Gio has a breadth of skills in formulation development, analytical and bioanalytical development, enzymatic assay development, QC, and a host of release, characterization, and stability-indicating assays for different classes of drug substances and drug products. Gio is always willing to take on the next project or job assignment. His annual performance was consistently solid, and he is quick to learn new tools and adapt to constant change which makes him a great asset in any fast-paced working environment.

Francois Nicol, Ph.D.

I strongly recommend Gio in the areas of formulation development and characterization, as well as analytical and biochemical method development. I worked alongside Gio for two years at Halozyme and rapidly found out that he has a broad knowledge in formulation and device technologies (fueled by a strong scientific curiosity), and he applies this knowledge very efficiently to new challenges. While at Halozyme, Gio demonstrated a strong ability to develop analytical and biochemical assays using a systematic approach based on strong technical skills and eclectic scientific foundations. Gio is a very productive individual who is always eager to design and execute the next experiment that will lead to a better understanding of critical formulation parameters or assay variables, or that will lead to further optimizations. Gio also has a strong understanding of the requirements for clinical stage formulations and analytical testing, which allows him to prepare for a smooth transition from pre-clinical to clinical development. Gio is very well organized and is always eager to use this skill to the benefit of project teams. He has strong collaborative skills and is a very hard-working, reliable and dedicated person who always keeps himself motivated and has a positive attitude in the lab whatever the circumstances.
