His growing interest in chemistry led him to start his own laboratory in a garden shed using chemicals bought from a supplier in London, with his main area of focus being the creation of "dyes and explosive compounds".
[1] After the discovery of Insulin in 1922 Morgan became interested in medicinal chemistry, and he applied to West Ham Municipal College, where he studied for his Master of Science part-time while still working for the Gas Light and Coke Company.

While attending lectures at University College London he met Glen Anrep, who he worked for as an unpaid volunteer, thus getting the physiology qualification he needed to apply for a PhD.

He attended the 1929 International Physiological Congress in Boston where he met several distinguished scientists including Walter Goebel and Michael Heidelberger, both of whom became close friends.
In 1936 he was awarded the Rockefeller Foundation Fellowship, allowing him to study at the Swiss Federal Institute of Technology Zürich under Tadeus Reichstein, who he also became friends with.
