About the Lab and Group

What distinguishes my translational (bedside to bench to bedside) research program from most others’ in the Faculty is that it is both clinical and laboratory-based. My long-term research focus has been in clinical pharmacokinetics and pharmacodynamics (particularly as these disciplines relate to: women's health; effects of gender, age, and other pathophysiologic states on pharmacokinetics and pharmacodynamics; and novel approaches to therapeutic drug monitoring), with more recent interests in pharmacogenetics and pharmaceutical outcomes evaluations.

Every day, I use my clinical practice experiences to identify relevant pharmacokinetic/pharmacodynamic/pharmacogenetic problems that are then studied in the laboratory. As such, our research team (specific for each project) consists of clinicians and laboratory scientists and a full array of trainees (BSc, MSc, PharmD, and PhD students; pharmacy residents; and postdoctoral fellows).
As an integrator who bridges the gap between the basic and clinical sciences, the goal of my translational research program is to address clinical problems from a qualitative, quantitative, and mechanistic perspective and to make a difference in the health and well-being of patients (i.e., study results are directly and immediately incorporated into patient care).

Training Environment

“Your profession is not what brings home your paycheck. Your profession is what you were put on earth to do with such passion and such intensity that it becomes spiritual in calling.” ~ Vincent Van Gogh

“It is the preceptor who sets the tone of the training program. He accomplishes this by what he does personally, by what he stands for, by the contributions he makes to his profession, by his actions and by his sense of values. The religious precept that one must lose himself to find himself is certainly true of the preceptor. The life of a dedicated preceptor is the endless pursuit of goals, many of which are unattainable.” ~ Donald E Francke

Projects

Immunosuppressant Pharmacokinetics, Limited Sampling Strategies, and Pharmacogenetics

These projects characterize the pharmacokinetics of (and develop limited sampling strategies for) mycophenolate and tacrolimus in lung, heart, kidney, and islet transplant recipients and ascertain the contribution of genetic polymorphisms (e.g., UGT and ABCC2) and other factors to inter-patient variability in pharmacokinetics of mycophenolate and its glucuronidated metabolites.

Impact of Various Pathophysiologic Conditions on Pharmacokinetics and Pharmacodynamics

These projects evaluate the pharmacokinetics and pharmacodynamics of various drugs in patients with various pathophysiologic conditions [e.g., intravenous immunoglobulin (IVIG) in patients with recurrent pregnancy loss (prior to and during pregnancy) and in patients with other immunologic conditions, etc.].

Stability of Medications in Extemporaneously Prepared Formulations for Use in Pediatric Patients

These projects evaluate the stability of various extemporaneously-compounded oral and intravenous formulations and apply the results immediately to care of pediatric patients

Various Other Pharmacokinetics, Pharmacodynamics, Pharmacogenetics, and Pharmaceutical Outcomes Studies as Co-Investigator.
