Carl began his tenure at The University of Oklahoma College of Pharmacy in August of 1997 as dean and assumed the role of regular faculty in November of 2002. Before returning to Oklahoma in 1997, he was a member of the professional staff of the American Council on Pharmaceutical Education, serving as Associate Executive Director from 1995 to 1997. Prior to joining the ACPE, he was Principal Pharmacologist and Group Leader at Zeneca Inc. From 1970 to 1987, he was a faculty member at the University of Wisconsin School of Pharmacy (Assistant Professor, 1970-1975; Associate Professor, 1975-1981; and Professor, 1981-1987). Carl holds a baccalaureate of science degree in pharmacy from the University of Oklahoma and M.S. and Ph.D. degrees in pharmacology from The Ohio State University College of Pharmacy. He is a registered pharmacist in the state of Oklahoma and a member of the Oklahoma Pharmacists Association.

As a faculty member at the University of Wisconsin-Madison School of Pharmacy in the pharmacology curricular area, Carl’s activities relating to pharmacy education principally involved the teaching of autonomic and cardiovascular pharmacology. He was selected to receive the Outstanding Professor Award three times.

Carl’s research has predominantly been in the general areas of autonomic, pulmonary, and cardiovascular pharmacology. His early work led to the development of new avenues of research related to autonomic regulation of allergic mediator release. Subsequent studies on the role of mediators in allergen-evoked modulation of smooth muscle tone resulted in a more intense focus for his research on the pulmonary system, especially on the regulation of the airways. Carl’s research focus in the pharmaceutical industry was on pulmonary pharmacology and drug discovery. This work led to the marketing of a novel anti-asthmatic drug, namely the leukotriene receptor antagonist zafirlukast (Accolate). Subsequent directions at Zeneca resulted in the initiation of a discovery program leading to the identification of potent and selective compounds capable of blocking receptors for certain natural peptides as potential clinical candidates for the treatment of asthma.

As a member of the professional staff at the American Council on Pharmaceutical Education, Carl’s work focused on the standards by which professional programs in colleges and schools of pharmacy are measured and the quality criteria that constitute the basis for recognition of ACPE-approved providers of continuing pharmaceutical education.

A revised doctor of pharmacy degree program and a non-traditional pathway to that degree were developed at The University of Oklahoma College of Pharmacy during Carl's tenure as dean. Also as dean of the college, he was involved in helping enhance the college's commitment to pharmacy education and research as well as to the principle of life-long learning in pharmacy through continuing education. Outreach was accomplished by providing focus and direction for the development of a new college of pharmacy web site and its use to enhance communications with all interested individuals. The involvement of Oklahoma pharmacists in the life of the college was emphasized as an important means of sharing, in the educational arena, goals and ideals for the advancement of the profession. Strong support of alumni in those activities was promoted as well through the establishment of the OU College of Pharmacy Alumni Affairs Board. In an effort to enhance cultural competence of the college, Carl was actively involved in promoting pharmacy to diverse cultures in the state and nation. Along with Lloyd Williams of Tulsa, Carl was involved in establishing the Tulsa Pharmaceutical Association, a local branch of the National Pharmaceutical Association. Additionally, he fostered the development of pharmacy education in northeastern Oklahoma by initially establishing programmatic elements and eventually a full degree program in pharmacy on The University of Oklahoma’s Schusterman Center campus in Tulsa. Preservation of the precious and scarce artifacts and documents related to the heritage of The University of Oklahoma College of Pharmacy and of pharmacy in the twin territories and state of Oklahoma has been an objective that Carl initiated as dean and continues to pursue as a faculty member.
