Mandeville, LA - Mark Batzer, one of LSU's most distinguished researchers and professors died on January 21, 2026 at the age of 64 years. Mark Batzer, born October 26, 1961, in Detroit, was the only child of Douglas and Marie Batzer. Born prematurely, he entered the world with the same resilience that defined his family.

His father, Douglas, was a World War II pilot whose plane was shot down five times. Each time, he survived with the help of the underground before returning home to serve as a Detroit firefighter and later working as a tool and die technician. His mother, Marie, an orphan who lived with a damaged heart valve caused by untreated strep throat, was known for her deep kindness and gentle spirit. Mark was preceded in death by his beloved parents.

After moving to Florida to help care for his grandparent, Mark attended a high school where few students pursued college. Encouraged by an inspiring teacher, he discovered a passion for biology. He once considered becoming a veterinarian, but after the painful loss of his beloved dog, he turned his focus to genetics. Detail-oriented and hardworking, Mark showed determination early riding his bike to the flea market to find the highest-quality coins for his boss and working as a stock clerk at Winn-Dixie.

Mark was proud to attend Michigan State University. Paying out-of-state tuition meant sacrifices—his parents shopped at Goodwill, and he worked in the cafeteria and dorms while keeping up with his studies. At MSU, he earned both his bachelor's and master's degrees, built lifelong friendships, and cheered on the Spartans. Though undersized, he helped win an intramural basketball championship and even walked on to the wrestling team—before deciding he was better suited for the safety of the lab than the mat.

While pursuing his doctorate at LSU under Dr. Bill Lee, Mark met the love of his life, Dr. Pam Richard. During Pam's years in medical school, he completed postdoctoral training at LSUMC with Prescott Deininger, where he began his pioneering work on mobile genetic elements. He later contributed to the Human Genome Project at Lawrence Livermore National Laboratory in California.

Mark and Pam, a devoted pediatrician, returned to Louisiana and built a life rich in friendship, travel, and shared adventure. Over 35 years of marriage, they made cherished memories with friends and neighbors, explored all seven continents, and visited more than 65 countries together.

Mark was profoundly honored to be named an LSU Boyd Professor—the university's highest academic distinction—and remained especially grateful to Dr. Mary Lou Applewhite for her steadfast support.

The Batzer Lab grew into a dynamic community defined by curiosity, rigor, and integrity. Over his career, Mark published more than 300 peer-reviewed articles, including many in premier journals such as Science and Nature, with 17 featured as cover stories. He was internationally recognized for his pioneering work on transposable elements and their role in shaping eukaryotic genomes and human genetic variation.

In 2001, he founded the LSU Genomics Core and, as its director and primary supporter, generously subsidized research across campus. His leadership strengthened countless projects, advanced the work of fellow investigators, and helped train generations of graduate students and postdoctoral fellows within LSU's Department of Biological Sciences and beyond.

A devoted mentor, Mark guided many graduate students—at least 12 of whom went on to become faculty members. In one remarkable year, seven of his PhD students graduated simultaneously. He was also a beloved professor who mentored numerous future physicians through his classes and laboratory, maintaining friendships with his trainees long after their formal training had ended.

Mark's life was a testament to resilience. Despite serious health challenges, he believed deeply in living fully and staying positive—proof that numbers never tell the whole story.

After a massive heart attack in England 20 years ago left him with an ejection fraction of just 15 percent, he persevered with the devoted care of his cardiologist, Dr. Farhad Aduli. The following year, he faced testicular cancer with humor, lightening the moment with his trademark jokes. Four years later, he survived a critical arrhythmia while playing softball—rescued by the very first responders he was playing alongside. In 2021, during repeated defibrillations for recurrent atrial fibrillation, he calmly reminded everyone to stay "easy going."

Before his passing from cardiac shock, he received compassionate care at EJ Hospital from Dr. Lick, Dr. Vukelic, Dr. Pierre, dedicated cardiac fellows, ICU nurses, and staff. We are deeply grateful for every effort made on behalf of his remarkable, battle-worn heart.

Mark will be deeply missed by all who knew him. His service on January 30, 2026, at Grace Funeral Home was filled with both tears and joy and was well attended. A scientific symposium and celebration of life will be held April 25, 2026, at LSU.

Mark always said, "Think positive." And, as he would add with a smile—Geaux Tigers!
