Jorge Armando Gonzalez Chapa, MD, PhD

Biography: Dr. Chapa was born in Coahuila, Mexico. He attended medical school at Universidad Autonoma de Nuevo Leon. He later completed a Master of Science and a PhD with specialty in immunology. Part of his postgraduate training was made at Texas Tech University Health Sciences Center and at the University of Hamburg, in Germany. Through his training he developed an interest in the local and systemic immune response in different arthropathies, such as septic arthritis. In 2020 he was awarded with the European Bone and Joint Infection Society best papers award and in 2021 with the summa cum laude PhD distinction. His current research interests are based on translational research in autoimmune diseases and how neutrophils and mitochondria might play a major role for the progression and severity of these types of diseases. Dr. Chapa is currently working in Dr. Lood's Lab.

Marina Barguil Macêdo, MD, MSc

Biography: Dr. Macêdo was born in Teresina, PI, Brazil. She graduated in Medicine on the Federal University of Piauí – Brazil, in 2016. During graduation, she took part in scientific projects developed on the Laboratory of Immunogenetics and Molecular Biology, conducting researches on the area of HLA haplotyping, renal transplantation, and bioinformatics, which concurred to the development of the online platform EpHLA-Converter (, an integrated database for histocompatibility analysis on kidney transplantation. Also, during graduation, she was the Scientific Director of the Academic League of Oncology, from 2013 until 2014.She obtained a Master of Sciences degree in Immunology in 2017, on the Biomedical Sciences Institute of the University of São Paulo – Brazil. She developed her thesis on the area of immunometabolism of macrophages, within the scope of macrophage polarization in a murine model of tubulointerstitial kidney disease.From 2018 until 2020, she was Resident of Internal Medicine on the Federal University of São Paulo - Brazil, having also participated on the Academic League of Internal Medicine.From 2020 until February 2022, she was Resident of Rheumatology on the Clinics Hospital of the University of São Paulo – Brazil. During her training in Rheumatology, she took part in a trial on the role of vitamin D supplementation in acute covid-19 (DOI: 10.1001/jama.2020.26848), and conducted a meta-analysis about the relationship between osteoarthritis and atherosclerosis (DOI: 10.1016/j.exger.2022.111734). Dr. Macêdo’s current research interest is on the pathophysiology of Systemic Lupus Erythematosus, with a focus on mitochondria dysfunction. Dr. Macêdo is currently working in Dr. Lood's Lab.

Ting Wang , MD, PhD

Senior Fellow
Biography: Dr. Wang was born and raised in Hebei, China. She attended medical school at University of Hebei in 2008. She completed her Ph.D. training in rheumatology in Peking Union Medical College and Chinese Academy of Medical Sciences. In 2016, she was awarded a fellowship by China Scholarship Council, which allowed her to pursue a one-year research project at the Division of Rheumatology at the University of Washington under the mentorship of Dr. Keith Elkon and Dr. Natalia Giltiay. Through this training, she developed interest in mechanisms underlying the development of pathogenic autoreactive B cells in autoimmune disease and decided to pursue further training in translational research in rheumatology. In 2019, she joined the Department of Rheumatology as a senior fellow to pursue post-doctoral training in Dr. Giltiay’s Lab. Her current research interest is developing effective biomarkers that are predictive of treatment response of Abatacept in RA. Dr. Wang is currently working in Dr. Lood's Lab.
