Gert Grobler


Dr. Gert Grobler is a scientist, educator and explorer. He joined several expeditions to the Sub-Antarctic Prince Edward Island archipelago where he investigated the genetic relationships and phylogeographic patterns observed within the Ectemnorhinus-group of weevils (Coleoptera:Curculionidae). The rationale of this study was to improve our knowledge on the species dynamics and biogeography of the Ectemnorhinus group of weevils in order to make scientifically based informed decisions on how to conserve this unique group of weevil species. This information served to guide informed conservation recommendations. Gert obtained his PhD from the University of Pretoria in South Africa. As the promotion of scientific exploration is very important to him, Gert founded DIYBIO Hong Kong to serve as a platform through which citizen scientists can explore and share the wonders of the natural world.

Maria Li

director &


Maria is a lifelong learner with a passion for pioneering new territory. Her interests are as diverse as life itself, however four main passions have percolated to the top of her list: biotechnology, education, entrepreneurship, and tinkering. In 2014, Maria got her first exposure to synthetic biology as a university student joined the iGEM competition to genetically engineer bacteria that help people to lose weight. Since then she started coming up with much more strange ideas and want to make it real. Her long-term goal is to become an inventor-educator so that she can combine her passion for research with her desire to teach and share knowledge with others.

Mike Yuen

lab engineerer

I am a graduate from CUHK in 1980 studied Biology and Biochemistry. After graduation, I got my Postgraduated Certificate in HKU and become a teacher. I have worked in Radioisotope unit, HKU as a teaching assistant and do some research in radiation effect in biological systems, also have some transgenic plants research in Botany Department as well. After I retired from my teaching post in secondary school. I would like to do some innovative projects in synthetic Biology and STEM education so I joined DIYBio-HK in MakerBay. Our organization can provide a good platform for all citizens in Hong Kong to get the hand-on experience in their projects. I like to share my skills and idea in electronic projects, biology knowledge, 3D printing, arduino and CAD/CAM works with our members. I really love DIYBio-Hong Kong.

Reynald De Guzmen

Summer intern

Hello! I am Reynald and I am a self-taught naturalist with a passion for biology and new ideas. I am mostly invested in the study of entomology and animal behaviour. in my free time, I rear and collect insect specimens and share whatever insights that come my way. Although my goal is to broaden our understanding of what is already known, I take long for the exciting journey that would take me there and hope you’d join us on that adventure!

Sunny Lai

Summer intern

As a year-three science student majoring in biotechnology in HKU, Sunny is interested in a lot of things: biology, DIY, volunteering… and eating delicious foods! After coming back from a service trip in Nepal this summer, Sunny joined DIYBIO and became one of the interns. He doesn’t know much about insects, but he is not afraid of insects (he was surrounded by different kinds of insects in Nepal for a month!) and is willing to do some “bug hunting” in Hong Kong! He is fascinated by agar art recently and would like to create some masterpieces in the DIYBIO lab.

Ben Lee

Summer intern

I am a 4th year student from University of Washington in the USA, and currently back in Hong Kong for summer vacation. Being a major in evolutionary biology, I am extremely passionate in nature, particularly in Arthropods such as spiders and insects. I enjoy hiking, kayaking, and lay down to enjoy nature in my free time; I also raise many different kinds of insects and spiders. I came across DIYBIO HK one day randomly on a Facebook Tarantula group, and now I’m now happily working as an intern for them.
