Doctor of Philosophy
Program Admissions Requirements
In addition to the general Graduate School admission requirements, this program has additional specific requirements.
Students with a major in the sciences, who have demonstrated above-average scholastic ability, are eligible. Minimum undergraduate course work should include: biology (8 credits), inorganic chemistry (8 credits), organic chemistry (8 credits), physics (8 credits), algebra (3-4 credits), and calculus (3-4 credits).
Fields of Research
There are eight general areas of physiology in which students may conduct research. Both human and animal models are studied.
Current projects are directed to study the overall control of the cardiovascular system with emphasis on the neurohumoral control of arterial pressure and the interactions of the renal body fluid volume system. Regulation of cardiac output and local regulations of flow in the microcirculation is also being studied in depth. (Drs. Cowley, Greene, Liang, Lombard, Munzenmaier, and O’Connor)
Computer Simulation of Biological Systems:
Computer modeling of the complex interactions of the variables involved in the overall regulation of the cardiovascular, respiratory, and renal fluid volume control system. (Drs. Cowley, and Greene)
Current research is related to the renin-angiotensin-aldosterone system, vasopressin, and prostaglandin with emphasis on the role of these systems on the control of body fluids, electrolytes, and arterial pressure regulation. (Drs. Cowley and Raff)
Current research focuses on the identification and characterization of gene(s) involved in the development of complex disorders in humans and rat models. Research includes QTL mapping, linkage and association analysis, haplotype and linkage disequilibrium analysis of single nucleotide polymorphisms, correlation of genetic polymorphisms to gene and protein expression, and development of transgenic animal models. Projects currently study genetic risk factors for cardiovascular and renal disease, obesity, diabetes, and brain disorders. (Drs. Jacob, Kwitek, and Michalkiewicz)
Molecular and Cell Biology:
Research areas include cell membrane channels and their modulation by neurotransmitters, humoral agents, local factors and drugs, regulation of cardiac myosin heavy chain gene expression, cardiac hypertrophy, and DNA binding proteins. (Drs. Jacob, and Wakatsuki)
Research areas include the importance of the kidney in the regulation of fluid and electrolyte homeostasis and blood pressure, the importance of autocrine, paracrine, and hormonal factors in the regulation of renal tubular and vascular function, and the elucidation of the factors important in the development of renal ischemic and hypertensive disease. (Drs. Liang, Cowley and Mattson)
Aspects currently under study are: the role of the carotid chemoreceptors and medullary, pontine, and cerebellar nuclei in the control of breathing. Specific emphasis is on respiratory rhythm and pattern generation and chemosensitivity. Studies are targeted to gain insight into central and obstructive sleep apnea, the Sudden Infant Death Syndrome, and Congenital Central alveola hypoventilation. (Drs. Dwinell, Forster, Tryba, Pan, and Hodges)
Ongoing projects relate to the role of circulatory smooth muscle in hypertension. (Drs. Greene, Harder, and Lombard)
The emphasis of our PhD program is to provide training in whole animal integrative Physiology as well as cellular and molecular Physiology. To achieve this objective, all PhD students are required to complete a two year, 4 semester, sequence of courses.
All students are required to take General Human Physiology (08202), but to fulfill the 9 credit requirement for each semester, the student and their advisor choose courses that best meet the students career needs. Course selection can be specific to Physiology (see below) or from other MCW departments or other institutions in Milwaukee. At the completion of this sequence, all students will take the written and oral comprehensive examination. For all years of graduate study, students will enroll each semester in Special Problems in Physiology (08275). They will also enroll in a Seminar Course (08300) each summer.
Matriculating students will begin by attending the first orientation session offered in early July. For the remainder of July, the students will spend one day in the laboratory of as many faculty as possible. By August 1, they need to have selected the three laboratories they would most likely complete their research. They will then spend three months in each laboratory while taking courses. The major purpose of these rotations is to facilitate the students’ deciding the primary laboratory for their PhD research. Since students are required to complete research in whole animal, cellular, and molecular physiology and because of the highly collaborative research by our faculty, most students will conduct research in the laboratories of their advisor and also in other laboratories. Students will thus have broad exposure and experience in the basic techniques of integrated physiology, molecular genetics and physiological genomics. At the end of each three-month rotation, the students summarize orally for ten minutes their experiences to the faculty.
