Our Team

The Janssen Human Microbiome Institute team combines our pioneering expertise in the microbiome with the drug discovery, product development, and commercialization know-how of a leading global biopharmaceutical company. Together with our colleagues at Janssen and Johnson & Johnson, we have the knowledge and resources to identify the most promising innovations taking place across the microbiome ecosystem and help our partners translate early-stage innovations into product concepts and, ultimately, new solutions with the power to impact human health.

As the Global Head of the Janssen Human Microbiome Institute (JHMI), Dirk deepens the Janssen R&D’s leadership, scientific understanding and capabilities in this emerging and exploding area of science.

Dirk joined from his most recent role as Senior Group Leader of Microbial Systems and Communities at the Broad Institute of MIT and Harvard. In this position, Dirk served as a scientific liaison between different organizational components, including the Broad Institute’s data generation platforms and both clinical and analytical collaborators on a number of microbiome-related projects. Dirk’s research efforts at the Broad Institute included the characterization of the microbial imbalance associated with diseases such as Crohn’s disease, type 1 diabetes and colorectal cancer. He was also involved with the National Institutes of Health (NIH) Human Microbiome Project (HMP), holding a leading role in the Data Analysis Working Group, consisting of over 50 investigators focused on human microbiome research.

Dirk received his Ph.D. in biochemistry from Ghent University (UGent), Belgium, and completed postdoctoral training at UGent and Massachusetts Institute of Technology in bioinformatics, comparative and evolutionary genome analysis and microbial ecology.

As the Head of Scientific Innovation of the Janssen Human Microbiome Institute (JHMI). Anuk is responsible for developing and maintaining partnerships across a multitude of collaborators and stakeholders working closely with the Johnson & Johnson Innovation Centers to solidify JHMI’s industry leadership position in delivering microbiome healthcare solutions.

Anuk joined the Janssen Pharmaceutical Companies of Johnson & Johnson in 2001 and has since catalyzed the evaluation of emerging areas of research with promising scientific potential for the Immunology Therapeutic Area (TA). Following a successful record of program and functional leadership spanning several disease areas focused upon the discovery and development of potential new medicines, she led External Research. In this role she delivered new areas of scientific research that shaped the Disease Area Stronghold (DAS) strategies for disease interception and prevention. Her work helped to establish a global network of external partners in academia and biotechnology for the Immunology TA and further drove investments in emerging areas of interest, including several ongoing projects focused on the microbiome. Most recently, Anuk served as Senior Director, Disease Integrative Biology (DIB), and launched the Immunology Exploratory Science Laboratory (I-ExSL) and Immunology Postdoctoral Program. As the founder of these groups, Anuk built productive scientific functions that leveraged human disease knowledge and the network pharmacology disease platform to establish new paradigms for identifying and validating novel therapeutic mechanisms.

Anuk obtained her BS (Honors) at the University of Bath (UK) in pharmacology and completed her Ph.D. in Pharmacology at the National Heart & Lung Institute, University of London (UK) focused on allergic inflammatory mechanisms. She has co-authored over 50 scientific articles, patents and patent applications.

As the Director of External Alliances of the Janssen Human Microbiome Institute (JHMI), Julie is responsible for driving excellence in Research Planning, Research Operations and Alliance Management across a range of partnerships from Discovery to Early- and Late-Stage Development in support of the JHMI's goal to accelerate the translation of exciting microbiome science into innovative products in multiple disease areas.

Julie most recently served as an independent consultant providing strategic program and alliance management services to clients in the biopharmaceutical industry. Prior to establishing her own consulting firm, Julie led the Corporate Alliances team at Harvard’s Office of Technology Development, aiming to maximize the value of existing alliance and research collaborations to the Harvard Faculty and Industry Partners. In this role Julie was responsible for a portfolio of ~$40M overseeing eight major drug discovery focused industry alliances encompassing over 35 projects. Julie worked to tailor alliance strategies to deliverables aligned with partner’s interest and desired value leading efforts to identify, monitor and guide scientific, publication and intellectual property strategy in the context of a drug discovery effort. Julie also led business development and marketing campaigns to establish and expand existing alliances with new projects. She joined Harvard’s Office of Technology Development in 2011 as an Alliance Manager and began leading the team in 2014. Prior to joining Harvard, Julie worked in Boston University’s Office of Sponsored Programs negotiating and administering federal and industry contracts in the life science space. Julie began her biopharmaceutical career at Merck Research Laboratories, Boston, in Drug Metabolism and Pharmacokinetics.

Julie holds a BS in chemistry from Villanova University and an MBA with a concentration in health sector management from Boston University.

As Product Development Scientist, Cian Hill is responsible for devising product formulation, manufacturing, and quality strategies for microbiome projects, which support and integrate into overall product development plans. He is also responsible for continued landscape analysis of microbiome innovation, globally.

Cian joined the JHMI team following more than two years with Johnson & Johnson (J&J) Sterility Assurance as part of the presitigous GOLD (Global Operations Leadership Development) program, which consisted of three placements across the J&J enterprise.

Cian’s first placement was in DePuy Synthes Ireland, working within the Quality Department as a member of the microbiology team. In this role, he gained knowledge of the quality regualtions for GMP manufacturing of medical devices and participated in a wide range of sterilization modalities.

He then moved to pharmecutical research and development within Drug Product Development at Janssen in Beerse, Belgium, where he focused on small molecule therapies. This role included work on an internal human microbiota pre-clinical microbiome drug, involving manufacturing capability development, method optimization, and preparation for a Phase 1 clinical trial. Cian spent his final GOLD assignment in Product Development & Manufaturing Sciences at Janssen in Cork, Ireland, where he focused on large molecule therapies with a primary responsibility on new product introduction processes and manufacturing of novel clinical trial material (Phases 1a – 2b).

Cian holds a Bachelors of Science in Genetics from University College Cork (Ireland). He obtained his Ph.D., with a focus on the gut microbiota of infants, from the same institution, in conjunction with the Alimentary Pharmabiotic Centre and Teagasc.
