When Jack arrived in the early 70s, he was fresh from his post-doc in vitamin-D biochemistry, and anxious to begin clinical investigation in rare patients with abnormal vitamin-D metabolism. While we were several years away from having our NIH Clinical Research Center, I had worked at the NIH GCRC for three years, so was able to help Jack conduct clinical investigations in these patients both at the Student Health Center, as well as in the Bernalillo County Medical Center with informed consent and institutional approval. These studies helped the School of Medicine establish credibility in clinical research when we submitted our GCRC grant request which was subsequently funded.
Jack pursued both basic and clinical research in this chosen field with extensive national recognition, while carrying a heavy teaching load including not only graduate students and post-docs, but also sharing teaching in the SOM Endocrinology and Metabolism blocks for freshman and sophomore medical students. Jack was a close friend, colleague, and scientist who significantly strengthened our science based educational curriculum for decades. He is missed, but not forgotten as one of strong members of the Biochemistry community with a strong commitment to basic and clinical investigation to advance the understanding of health and disease as impacted by Vitamin-D.
