Director of Scientific Innovation & Education, ProBiora Health

Dr. Rachelle Beattie McAliley holds a PhD in Biology with an emphasis in Microbial Ecology from Marquette University and has dedicated her career to the microbiome — the complex ecosystem of bacteria that shapes not just your mouth, but your overall health. As ProBiora’s Director of Scientific Innovation & Education, she oversees the research behind ProBiora3® and ensures that science actually reaches the people it was meant to help.

Dr. Beattie McAliley is a recognized voice in oral health science, presenting to dental professionals through organizations like AAOSH and IDMSS on topics ranging from the role of the oral biofilm to the evidence behind probiotic therapy in dentistry. Her work bridges the lab and the real world — helping patients, providers, and anyone curious about their health understand why the mouth matters more than most people realize.

Great science shouldn’t stay in the lab. Dr. Beattie McAliley brings it here — clearly, honestly, and with the conviction that a healthier mouth genuinely changes lives.
