Emeritus Team

Joseph Tedesco, PH.D
Joseph Tedesco, PH.D
Joseph Tedesco’s career has been in the field of biological chemistry. Before working with BeaconRD, he was often contracted as a scientist advisor to CRA (then known as Revenue Canada). There, he performed detailed science audits of SR&ED claims from most of the major pharmaceutical companies in Canada.
These audits involved, in total, claims of over 3 billion dollars.
Over the past 12 years, he has teamed with financial auditors in assisting many Canadian companies with the scientific and technological descriptions of their SR&ED activities.
He has two particular areas of scientific expertise that contribute to BeaconRD’s ability to assess and support such SR&ED work. First, he has a doctorate in neuropharmacology, working in the lab of Philip Seeman when they pioneered in the first identification of the dopamine receptor. Additionally he has a background in biochemistry. These disciplines enable him to deeply engage with a company’s scientists on projects ranging from biochemistry to clinical trials of drugs both new and old. Second, he has done considerable research on computational approaches to drug design. This latter expertise has often been used in critiquing SR&ED projects involving software development and information technology (IT).
Dr. Tedesco is qualified to assist SR&ED claims in pharmaceutical development, biochemical research, clinical trials, cosmetics, food products and certain areas of software development.
Joe was born in Toronto Canada and is a life-long Canadian citizen. He has an abiding interest in mathematical algorithms, chemical design, bicycling and mentoring young scientists.

Marvin Silbert
Marvin Silbert
In his role as Senior Manager, Chemical and Manufacturing, Marvin Silbert has successfully prepared several hundred SR&ED eligibility claims covering the development of a wide range of products and processes developed within the Canadian industrial sector. His clients have varied from very small to very large with some of the more exotic projects now operating on the International Space Station and down a few thousand metres into the ground.
Marvin initially, he pursued an academic career, but decided to move to industry and joined Ontario Hydro’s nuclear operations. He has successfully undertaken a number of projects that, although they took place before the inception for CRA’s SR&ED program, would have met all the criteria for fundamental scientific research (SR) and industrial process development (ED).
Marvin took that experience and became an independent consultant providing water-treatment optimization and troubleshooting services as well as training to a wide spectrum of industrial clients in Canada and the USA. He began working with Revenue Canada’s SR&ED program shortly after it was introduced and joined BeaconRD. He has remained involved with industry by providing technical advice to a number of major industrial plants in Canada along with a number of training courses in British Columbia, California, Dubai and Kuwait.
