After obtaining his medical license in 1988 and specialising in organ transplant, he went on to do his doctorate in immunology in Munich. In 1990 he opened a practice for general medicine in Bergheim, Germany where he began to diagnose and treat Lyme patients.
In 2006 he had founded the BCA-clinic, BCA-lab & Research facility and BCA-Training Academy, gaining worldwide recognition and praise for establishing successful diagnostic tools and treatment protocols. Over the years, it is these diagnostic tests and treatment plans that have helped thousands of chronic Lyme patients gain a better quality of life.
In 2016, he founded and became CEO of Infectolab Americas (USA) with the aim of developing high quality tests and rigorous testing procedures to raise the bar in diagnostic testing for viruses and bacteria (including Lyme and other tick borne diseases). This includes PCR (swab) and ELISA (antibody) testing for Covid19 Coronavirus.
Dr Nicolaus has been an active member of ILADS (International Lyme & Associated Diseases Society) since 2007, as well as the ILADEF (International Lyme and Associated Diseases Education Foundation) where he was treasurer from 2013-2018 and Board Director from 2011-2018. He is a certified training physician who has taught over 1,100 doctors since 2006.
Since 2008 he is a member of the medical advisory panel of the Charles E. Holman Morgellons Disease Foundation and has treated many Morgellons patients over the years through his clinic.
Dr Nicolaus currently divides his time speaking at conferences and webinars, training medical practitioners in diagnostics and treatment protocols, conducting clinical trials and furthering global research in tick borne diseases. He provides regular mentorship and training to a core group of clinics around the world, helping to train their staff and providing hands on consultancy to some of their patients with complex medical histories.
Dr Nicolaus is passionate about the work he does and advocates the need for continual knowledge sharing and the global collaboration of Lyme experts and researchers. It is only through this collaboration that we can better understand and therefore manage and treat patients with tick-borne diseases.
