Dr. Daren Calleemalay

Daren Calleemalay is a clinical researcher focused on pharmacokinetics and antimicrobial optimization in critical care and cardiac surgery settings. Published work centers on peri‑operative antibiotic prophylaxis and anticoagulation management, with particular attention to drug exposure variability in complex hospital populations.

Research in PLoS ONE examines cefazolin pharmacokinetics during cardiopulmonary bypass, applying population modeling and simulation to refine dosing strategies against surgical site pathogens. Complementary work in critical care evaluates anti‑factor Xa levels in patients receiving enoxaparin prophylaxis, highlighting the influence of weight and biochemical parameters on achieving therapeutic targets.

Based on the limited available publications, expertise lies in clinical pharmacology, therapeutic drug monitoring, and evidence‑based dosing optimization. Contributions support more individualized medication strategies in high‑risk surgical and intensive care populations, strengthening antimicrobial stewardship and thromboprophylaxis practices.
