Executive Team

Alden E. Masonis, PhD

Dr. Masonis has a PhD in pharmacology with an emphasis in neuroscience. He has extensive experience in data analysis and is a self-proclaimed data junkie. Alden received his doctoral degree from a joint program in neuropharmacology between Rutgers University Graduate School and the University of Medicine and Dentistry of New Jersey/Robert Wood Johnson Medical School. His thesis research established the first evidence for a direct interaction between androgenic and anabolic steroids and the Gamma Amino Butyric Acid receptor system in rat brain, establishing a potential link between the direct effects of androgenic hormones and one of many neurotransmitter receptor systems in the central nervous system. He has done significant work in preclinical development, clinical trial design, biomarkers and pharmacogenomics and is a self-proclaimed data junkie. He has substantial experience in bridging the gap between clinical development and pharmaceutical marketing and works closely with the team to ensure that all programs achieve their intended goals.

Donna J. Schroeder, PharmD

Dr. Schroeder has a PharmD from the University of California, San Francisco. Her clinical emphasis is in oncology, but she has a vast array of experience in many therapeutic areas. After completing two years of residency at UCSF, Donna joined the faculty and ran the Drug Information Analysis Service and was a preceptor for both students and residents on the General Medicine service. During this time she wrote and edited scientific papers, a journal column, and handbooks for pharmacy and nursing practitioners.

Donna has experience in translating preclinical work into clinical commercialization with her expertise in trial design, biostatistical analyses, and outcomes research. She stays abreast of current clinical developments that may impact drug design and delivery. Two of her most recent passions are the use of biomarkers to identify proper targets in drug development and helping her clients evaluate biosimilar products in a branded marketplace. Donna also has experience working with major institutions as well as small biotech firms to achieve optimal success of getting the attention for grant proposals such as R01s (NIH) and SBIR (Small Business Innovation Research) grants. Her drive is to assist in producing a grant that convinces the reviewers it deserves to be funded. Donna works with the P4S team to ensure all team members learn from each other, share experiences and collaborate so that the end goal of complete client satisfaction is achieved.
