Born, raised, and still residing in Vancouver, Kalla spends his days (and sometimes nights) working as an ER Physician in an urban teaching hospital. The idea for his first medical thriller, PANDEMIC, sprang from his clinical experience in facing the SARS crisis of 2003. He has written five science thrillers and or medical mysteries, delving into themes and topics as diverse as superbugs, drug addiction, prions, DNA evidence, pandemics and patient abuse. Kalla's sixth book, OF FLESH AND BLOOD, is a departure from the medical thriller genre. Featuring two multi-generational families, a major West Coast medical center and interwoven storylines, he tackles the human condition through the loves, lives and struggles of characters connected by lineage and bound by family secrets. His books have been translated into ten languages, and Pandemic and Resistance have been optioned for feature films. Daniel received his MD from the University of British Columbia. He is married and the proud father of two girls.
