Dr. Han, a biologist for 28 years and a former medical doctor developed AllerPops® (US Pat No._9,795,579).The discovery started with my family. From infancy, my son had allergies. As a medical doctor, a biologist, and of course a father, I wanted to find a solution. But how? The opportunity came when I developed allergies in 2014. I started to collect data on my allergic reactions. In the spring of 2017, I revealed the secret behind allergic reactions that nobody had discovered. The application of my newly found theory, AllerPops, relieved my family’s allergies shortly after.Biological research was not new to me when I began to study my allergies. I had been a biologist at Los Alamos National Laboratory (LANL) for 22 years, where I participated in the Human Genome Project, led a team to complete many hundreds of bacterial genomes, and authored more than 300 research papers. Before that, I got my Ph.D. from Fudan University. I was trained as a medical doctor in college and worked in a hospital for many years.“With purpose, simple things become enjoyable, and difficult things become opportunities to learn and overcome.”
