Dr. Guo received a 5-year MD and a 3-year MSc degree from China. He was an established medical scientist and clinician on liver diseases before his come to US (one of few who studied polypeptides and its immunity of native HBsAg in 1980’s; one of pioneers who studied HCV genotypes collaborated with scientists in Japan in 1992). His research on PBC and PSC molecular biology at Ochsner in US has laid the ground of the hypothesis of endogenous retrovirus may triggered biliary inflammation process in PBC patient. He has patented a DNA sequence that dominantly seen in liver tissues of patient with PSC. His work on hepatitis B demonstrated the presence of HBVDNA in liver tissue in patients with evidence of HBsAg clearance and in patients with HBcAb alone. Those findings supported prophylactic antiviral therapy in liver recipients with + HBcAb-donor.

After Hepatology/Transplant fellowship at Mayo Clinic in Scottsdale, Dr. Guo Joined Baylor University Medical center as a full-time staff transplant hepatologist and a liver consultant in 2005 until 2018. He has 15 years expertise on patient’s care and clinical medicine teaching both in general and transplant hepatology. He won multiple wards such as Vital Compassionate doctor awards, Patient’s choice awards, Top Physicians in America and Best Doctors in Dallas. Now Dr. Guo is to bring the opportunity for the harmonious integration of clinical expertise, and research experience on liver diseases to our patients with an emphasis on personalized patient-centered care. He currently specializes in treatment of all liver diseases with strong interests in preventing patient to develop and/or die from liver cirrhosis. Dr. Guo would like to continually proceed his passion on teaching of liver disease integrating with his personal understanding from clinical practice and previous research.

Dr. Guo’s interests outside of medicine include art collection and appreciation.
