Dr. Ptoton graduated from University of Nairobi with Bachelors of Science (Industrial Chemistry) with a First Class Honors. He then won and was awarded the prestigious Rhodes Trust Scholarship and was admitted to Oxford University for Doctorate Degree in Organic Chemistry. At Oxford University, Dr. Ptoton worked in Professor Timothy Donohoe Group where his Research Project involved Synthetic Methodology Development of simple and complex organic molecules using Ammonia-Free Birch Reduction Reactions. He also developed a multi-step synthetic route to synthesis of Natural Products which included (±)-Cyclindricine A and (±)-Cyclindricine C. He then graduated in 6th November, 2010 with Doctorate Degree and his thesis title is Synthesis of (±)-Cylindricine C and a Formal Synthesis of Cylindricine A.

After graduation, Dr. Ptoton was employed as Organic Lecturer at South Eastern Kenya University (SEKU) before he was promoted to be the Chairman of Physical Sciences at the School of Pure and Applied Sciences where he served until August, 2014. He then moved to Muranga University College as Lecturer of Organic Chemistry before he was appointed as the Acting Director for the Directorate of Research and Postgraduate Studies. A position he holds to date. Dr. Ptoton is also the Chairman of the Board of Trustee for National Environmental Trust Fund.
