Ab Matteen Rafiqi
Dr. Rafiqi has had extensive experience in insects' development and evolution. He initially studied the flies (Diptera: Phoridae and Syrphidae) where he explored the major steps in the evolution of extraembryonic membranes. He then switched to the ants (Hymenoptera: Formicidae) where he studied the evolution of endosymbiosis. Now he works with ants as well as true bugs (Hemiptera: Cicadellidae). He is broadly interested in exploring how development integrates genetic and environmental inputs into the phenotype - the primary target of natural selection.
The working idea in the lab is that endosymbiosis must be seen not as a relationship between two individual organisms but a phenomenon where the endosymbiont must integrate into the host developmental gene regulatory network such that they act as a single organism. He uses insects because they are the most speciose eukaryotic organisms on the planet and possess a remarkable degree of morphological, physiological and behavioral diversity.
Dr. Rafiqi expands upon the rapid advances in the field of evolutionary developmental biology (evo-devo) in the past few decades wherein the developmental genetic basis of this diversity in insects was studied in detail. Taking inspiration from the classical studies in embryology of insects done from the mid-19th to the mid-20th century, he wants to understand how genetic accommodation, genetic assimilation, developmental plasticity, and developmental endosymbiosis can be integrated into the study of evolution.

Scientific Impact
I firmly believe that the future of science lies in inclusive, collaborative communities—where talent from all backgrounds is nurtured, and scientific inquiry is guided by curiosity rather than barriers. By offering equal opportunities for all, regardless of race, gender, or socioeconomic background, we can unite a diverse set of minds to tackle the most complex and urgent challenges facing the world today. My vision is to contribute to reducing global disparities in both the quality of science and the scientists producing it. This can only happen when we actively empower and uplift those who have been historically marginalized or overlooked in traditional academic structures.
At BILSAB, I'm excited to be part of a collective effort to build a more inclusive and impactful scientific future, where our research contributes not just to academia but to solving global problems and creating positive changes in the world.
Ongoing work
Currently the lab works on two model organisms and several projects. Broadly these projects are aimed at understanding the mechanisms of major evolutionary transitions and the molecular genetic interactions between the endosymbiont and the host genes.
State of the art facilities and expertise for imaging, transgenesis, and genetic manipulation of insect embryos.
Vision
Dr. Rafiqi came to Turkiye from the University of Chicago and McGill with a vision to expand the availability of state-of-the-art scientific training beyond the developed countries. In this regard, he believes that basic science shall play a pivotal role in minimizing the disparity in scientific training as well as attitudes towards science in general and biology in particular. While translational science provides quick returns, basic science treads on untrodden paths to discoveries, making it possible to make a higher impact in the societies where it is undertaken. Studying basic sciences also allows the trainees to ask creative and original questions in their fields, which deepens their understanding of these concepts.
Approach
As a principal investigator, I'm committed to cultivating an environment of open access and inclusive mentorship. While many academic programs require formal training prerequisites, I strongly believe that talented students often remain untapped due to rigid educational systems. In our lab, we focus on hands-on engagement, giving students the chance to explore science through real-world research. Many of our current team members started as volunteers and, through guidance and personal growth, have transitioned into full-fledged scientists.
BILSAB has been an ideal environment for realizing this mentorship vision. The institute's flexibility and support for unconventional educational pathways have been crucial in allowing me to tailor mentoring practices to the unique needs of each student. This has made it possible to foster a scientific community where curiosity and collaboration drive progress, not rigid rules or hierarchies. BILSAB's openness to individualized learning and innovative training models has provided the perfect foundation to develop the next generation of researchers who are not only skilled but also driven by a passion for discovery.
About the team
Currently the lab has four Ph.D. students and one postdoc.
Mauricio E. Alarcón
is a native of Chiguayante, Chile. Early in his research, he studied parasitic symbiosis through flea-rodent and cat flea-gregarine interactions. Currently, Dr. Alarcón's research focuses on mutualistic interactions between bacterial endosymbionts and insects, examining the ecology of the species, their embryological development, and their evolutionary history. His long-term goal is to decipher how phylogenetically distant organisms become fully integrated, ultimately functioning as a single unit. He is currently leading the TÜBİTAK 1001 project which aims to track the developmental trajectory of the cells that become bacteriocytes in a species of leafhoppers called Anaceratagallia ribauti.
Zelal Özgür Durmuş
I am writing my doctoral dissertation with Prof. Ergi Deniz Özsoy at Hacettepe University, the Department of Biology and I am working as a research assistant in a TUBİTAK project directed by Ab. Matteen Rafiqi at Beykoz Institute of Life Science and Biotechnology.
My main fields of interest are endosymbiosis and developmental genetics. I seek to approach these two subjects within the framework of ecological, evolutionary, developmental biology. Furthermore, I am curious about the alteration of traditional evolutionary views within the context of the philosophy of biology. On a personal level, sharing ideas, giving speeches, and writing popular columns about science and evolution are some of my outreach activities. I am also a passionate nature observer, whether the birds, the sky, or the underwater.
Nihan Sultan Milat
a PhD candidate in the Rafiqi Lab. I'm fascinated by the complex question of obligate endosymbiosis: how hosts and their symbiotic partners co-evolve and communicate at the molecular level. To investigate this, I focus on ants, a group that showcases incredible biological diversity and intriguing symbiotic associations. More specifically, I study how the BMP signaling pathway shapes these endosymbiotic interactions and contributes to key developmental processes. By examining gene expression and pathway dynamics, I aim to uncover how molecular signaling governs the intricate crosstalk between the host and its endosymbionts. One of my favorite aspects of my scientific work is also a bit of an exploration: capturing the hidden beauty of endosymbiosis through microscopy, blending science with art, and I love every moment of it!
Beyond the lab, I love exploring new countries and immersing myself in different cultures. Science has also taken me on journeys around the world, allowing me to attend conferences, share ideas, and collaborate with researchers from diverse backgrounds. These experiences fuel my curiosity and passion for discovery!
Birgül Çolak Al
I am a PhD student with a background in Molecular Biology and Genetics, having completed my bachelor's and master's degrees in this field. This year, I started the PhD programme in the Laboratory of Ecological Evolutionary Developmental Biology at the Beykoz Institute of Life Sciences and Biotechnology to explore fundamental questions about the evolutionary and developmental biology of ants.
My research focuses on Camponotus floridanus, a model ant species that harbors the obligate endosymbiont Blochmannia. I study the Hox genes within the bithorax complex (BX-C), which are highly conserved transcription factors that determine segmental identity during embryogenesis in bilaterian animals. In ants, these genes have evolved beyond their canonical homeotic functions, exhibiting maternal expression that influences posterior development and germline formation. My work aims to uncover how the regulatory mechanisms of BX-C genes have evolved in ants.
Sevim Nur Akyüz
I am a PhD student and research technician with a background in Molecular Biology and Genetics, currently pursuing my PhD in Biotechnology at BILSAB. My work explores the metabolism of Blochmannia, the obligate endosymbiont of the Carpenter ant Camponotus floridanus.
My research focuses on Blochmannia's genes and metabolic pathways using advanced molecular tools to uncover how this bacterium supports its host and sustains the intricate metabolic interdependence between the symbiont and ant.
