Our Team

A genomic result is only the beginning. Its clinical value depends on professionals who can interpret its meaning, explain its implications and translate that knowledge into informed medication decisions. Dr Jennifer Marquez strengthens this essential connection between genomic science and patient care.

As Antares Genomics’ Chief Pharmacogenomics Officer since 2022, Jennifer brings together scientific leadership, professional education and a commitment to equitable access. Her contribution extends beyond the expertise she brings to our organisation: she develops that expertise in others, strengthening the local capability needed to make pharmacogenomics part of everyday healthcare.

Jennifer developed Antares’ six-month pharmacogenomics training programme, equipping pharmacists in Africa with the specialist knowledge and practical skills to provide pharmacogenomic consultations, support the interpretation and analysis of reports, and contribute to effective medication management in collaboration with treating clinicians. Her work reflects a fundamental principle of our approach: access to testing must be matched by access to professionals who can use its findings responsibly and meaningfully.

Through her creation and leadership of the teaching platform at AGPMC Academy, Jennifer has established an educational foundation that strengthens Antares’ precision-medicine offering. She translates specialist knowledge into practical learning, supporting pharmacists in their role as a vital link between genomic information, prescribing decisions and patient understanding.

An influential advocate for pharmacogenomics globally, Jennifer brings a particular commitment to Africa. She champions equitable access to testing alongside the development of local expertise—recognising that meaningful access encompasses both the availability of a test and the professional support needed to understand and apply its results.

Jennifer’s value to Antares is both clinical and strategic: she turns specialist knowledge into shared capability. Through education, clinical leadership and advocacy, she strengthens the human infrastructure of precision medicine—connecting the science we deliver with the people equipped to bring its value into patients’ lives.

Kishore has practiced genetic counseling for over four years. He holds an M.Sc. in Genetic Counseling from Kasturba Medical College, Manipal, and a B.Tech. in Genetic Engineering from SRM Institute of Science and Technology, Chennai. He assesses genetic risk, counsels patients and families before and after testing, builds pedigrees, guides test selection, and interprets molecular, cytogenetic and genomic reports across prenatal, reproductive, pediatric, adult, rare disease and hereditary cancer genetics. He also coordinates with treating physicians on complex cases. He has published in Clinical Dysmorphology and contributed to GeneReviews, with a focus on rare genetic disorders.

Sinead is an HPCSA-registered genetic counsellor based in Hilton, KwaZulu-Natal, offering online appointments across South Africa. She completed her undergraduate and honours degrees at the University of Pretoria, majoring in human genetics and physiology, with her honours degree in molecular genetics.

She completed her master’s degree in Genetic Counselling at the University of Cape Town, accompanied by a two-year internship at hospitals across the Western Cape, KwaZulu-Natal and the Northern Cape, including Red Cross Children’s, Groote Schuur, Inkosi Albert Luthuli, KZN Children’s, Greys and Harry Surtie Hospitals.

Since 2022, Sinead has been part of a multidisciplinary team of doctors, nurses and genetic counsellors from government and private practice on an annual outreach trip to the Northern Cape. The team identifies people at risk of Lynch Syndrome, offers genetic testing, delivers results and, where positive, provides relevant screening such as colonoscopies and gynaecological exams. The NGO Pink Drive forms part of the wider team, providing breast exams, pap smears and prostate exams. With genetic, gynaecological and gastrointestinal services limited throughout these rural districts, many people would die from Lynch-related cancer if not for this annual outreach drive.

Since 2021, Sinead has served as the private practice representative on the national committee of the Genetic Counsellors of South Africa (GCSA).

Dr Jeanie Magdalena Gatewood is a clinical research executive, oncology nurse leader, scholar-practitioner, and patient-safety advocate whose career spans the continuum from scientific discovery and clinical development to the patients ultimately affected by those decisions.

She serves as President, Phase I/First-in-Human Clinical Research at Advanced Research Institute (ARI) and Principal of Gatewood Global, an independent clinical research strategy firm. At ARI, Dr. Gatewood leads the development of early-phase/first-in-human capabilities while contributing to a broader multi-site research organization conducting clinical trials across therapeutic areas and stages of development. ARI brings more than 25 years of clinical research experience and reports more than 400 completed studies, with an emphasis on enrollment, data integrity, trial execution, and participant safety.

Dr. Gatewood also advises Antares Genomics, whose precision-medicine work and 108,000 African Genomes Project are advancing more representative genomic evidence and its translation into meaningful patient benefit. Her work explores patient safety as an interconnected system — from genomic representation, AI-enabled discovery and organizational decision-making through clinical trial design, first-in-human exposure, site execution, transparency, and ultimately patient care.

Drawing on executive leadership experience across research sites, sponsors, CROs, academic medical centers, biotechnology, and healthcare software solutions, Dr. Gatewood brings a uniquely cross-functional perspective to safe, participant-centered clinical development across Phases I–IV. A frequent international speaker and published researcher, she works with sponsors, CROs, investigators, and technology innovators to translate promising science into clinical research that is operationally rigorous, ethically grounded, data-driven, and centered on the people it is intended to serve.

Ziyaad Parker is an experienced data management professional and strategic advisor with expertise spanning data governance, analytics, data architecture and information technology strategy. Having begun his career in software development, he combines a strong technical foundation with a senior, business-focused perspective on how organisations manage and derive value from their information assets.

His work focuses on strengthening data quality, improving reporting and performance management, and developing practical governance frameworks that support informed, evidence-based decisions. Ziyaad bridges the gap between complex technical environments and executive priorities, helping leaders understand not only what their data reveals, but also the systems, processes and accountability needed to use it effectively.

Grounded in practical execution and responsible data stewardship, Ziyaad’s approach connects technology with organisational purpose. He brings to Antares a valuable combination of technical fluency and strategic judgement, supporting the strong data foundations essential to its work in precision medicine. His perspective reinforces Antares’ commitment to treating data as a carefully governed resource whose value lies in the knowledge, decisions and meaningful benefits it can enable.
