I started to know Hamed three years ago when he joined Reata as a Computational Chemistry Postdoc. Since then, I have been collaborated closely with him on medicinal chemistry projects. Hamed applied his in-depth knowledge on computational chemistry to support molecular design, interpret biological data, and provide insights into drug-target protein interaction at molecular level. Hamed has been an excellent team player. He worked independently, provided feedback efficiently, and communicated with medicinal chemists very effectively. I am glad having worked with him and have no hesitation recommending him to any potential employers.

I received tremendous mentorship from Hamed during my Ph.D. journey at the University of North Texas Health Science Center while he was doing postdoctoral research with Dr. Jin Liu. Without his encouragement and guidance, I may not be able to complete my PhD training and get an industrial job working as a computational biologist. When I did a research rotation with Dr. Jin Liu, I had zero ideas about molecular docking, shell script, and Python programming. Hamed used to sit with me to explain my project, from key ideas to essential techniques. Impressively, he fully answered my questions and helped me build crucial concepts using vivid examples during our discussions every time. Most importantly, there was no formal curriculum for computational chemistry in our school program, and Hamed helped me with finding good material. During the reach rotation in Dr. Jin Liu’s lab, Hamed coached me to complete an interesting cyclic-peptide docking project leading to my first co-authorship publication (Angew Chem Int Ed Engl. 58:15904-15909) during my PhD study. With Hamed’s inspiration, I continued my PhD journey in Dr. Jin Liu’s Lab. Again, with his straight-to-the-point advice and techniques training, I was able to complete several projects inspired from his ideas. For example, I learned how to use machine learning (Random Forest) to assist my SpyCas9 protein designs from his published AI studies. Inspired by his idea and technical support, I was able to utilize CPPTRAJ tools (Amber) to write codes interrogating SpyCas9 for the protein structural modulations. For me, Hamed is a great mentor and a life-long friend. It was my pleasure to do research with him and learn from his critical thinking during almost 3 years. I believe Hamed will bring tremendous value to any company with his creative ideas, computational expertise and experienced mentorship skills. Duen-Shian Wang
