Developmental Biology, Sex Determination, and Fertility

How does the embryo decide to become male or female? One early decision can shape an entire organism.

Research focus: The lab studies genetic and molecular mechanisms that control sex determination and fertility in mammals. Research examines how key genes and regulatory elements function during embryonic development and how disruptions lead to disorders of sexual development and infertility. The lab also develops innovative cellular models (including artificial testis models) to study sperm formation and sex reversal.

Highlighted takeaway: Sex determination and fertility lie at the heart of human development and reproductive health, bridging basic biology and clinical medicine.

CRISPR-Based Gene Editing and Gene Therapy

Can we fix a genetic disease at its source, the gene, instead of treating symptoms?

Research focus: The lab develops CRISPR-based gene therapy approaches in stem cells, focusing on severe blood and immune-system genetic diseases. Research aims to precisely correct mutations in a patient’s own cells to restore function and rebuild a healthy immune system. The goal is to translate gene editing from an experimental tool into durable, clinically viable solutions.

Highlighted takeaway: Gene therapy can enable one-time cures for diseases once considered incurable, redefining modern medicine.

Biology of Aging and Protein Folding

Why do age-related diseases appear late in life? Because cellular quality control  loses precision.

Research focus: The lab explores how aging biology connects to protein folding and neurodegenerative disease. Using genetics and model organisms, the research maps molecular pathways that regulate aging rate and long-term protein quality. A key insight: aging and age-related disease are intertwined, protein-quality failures can trigger disorders like Alzheimer’s.

Highlighted takeaway: Molecular understanding of aging can enable healthier aging and generate future therapies for age-related disease.

Transcriptional Control and Gene Expression

How does a cell “know” which gene to activate, and when? Gene expression is like a sound mixer - volume, timing and context matter.

Research focus: Each cell contains thousands of genes, but only a small fraction are active at any given moment. Our lab studies how transcription begins and how this step is tuned to control whole gene networks during development. A major focus is the core promoter: a short DNA region where tiny changes can reshape gene activity across the cell, sometimes across the whole organism.

Highlighted takeaway: Tiny DNA changes, even a few base pairs in a core promoter motif, can alter development and organ function. Using Drosophila, we uncover how embryonic gene networks are regulated, with relevance to human biology, biotechnology, and medicine.

Protein Degradation and Human Disease

How do cells decide which proteins to keep and which to destroy? Mistakes in this decision can cause disease.

Research focus: Proteins perform nearly all cellular functions, from building cellular structures to catalyzing chemical reactions, making their precise regulation essential for life. Proteins that are damaged, mislocalized, or no longer needed must be removed in a timely manner. The Koren Lab studies how cells recognize such faulty proteins and how failures in these pathways contribute to diseases, including cancer and neurodegeneration.

Highlighted takeaway:Protein degradation is essential for life- understanding how cells control protein turnover reveals fundamental biology and opens new paths for treating disease.

RNA Biology and Cellular Dynamics

What happens to RNA from birth to death? Much more than ‘message delivery.’

Research focus: RNA is dynamic: it moves, changes, responds to the environment, and shapes cellular behavior. The lab tracks RNA life cycles, synthesis, processing, transport, export, storage, and degradation, often in real-time inside living cells. By imaging single RNA molecules, the research links RNA dynamics to stress responses, cancer, and disease.

Highlighted takeaway: Disrupted RNA dynamics are implicated in many diseases, from cancer to neurodegeneration, understanding RNA adds a deeper layer to cell biology.

Peroxisome Biology and Human Health

How can a tiny organelle drive major disease? When peroxisomes fail, consequences can be wide-ranging.

Research focus: Peroxisomes support critical cellular processes; dysfunction can contribute to rare genetic disorders and common diseases. The lab studies how peroxisome biology connects to rare diseases, obesity, and male fertility, and where therapeutic intervention may be possible.The work bridges molecular/cellular research with collaborations across medicine, biotech, and patient organizations.

Highlighted takeaway: Understanding the cell from the inside is the foundation of precise, innovative medicine, from organelles to clinical impact.

Protein Trafficking and Cellular Health

Every cell in our body relies on a trafficking network that makes sure all proteins safely arrive at their cellular destination. When this routing fails, protein “traffic jams” are generated inside cells and contribute to diseases such as Alzheimer’s and cancer.

Research focus: The lab studies the extensive protein trafficking network that transports billions of proteins from where they are made to where they’re needed. Research addresses how this system is regulated, how cells recognize and remove defective proteins, how trafficking pathways go wrong in disease, and how these failures might be fixed to restore healthy cellular function.

Highlighted takeaway: Understanding protein trafficking is essential because its malfunction underlies many devastating diseases and offers targets for new therapeutic strategies.

Cell Cycle and Cell Growth

Why do cells decide to divide or not? Cells coordinate growth and division through decision‑making circuits that balance size, proliferation and molecular timing.

Research focus: The lab investigates the physiological and molecular dynamics of proliferating mammalian cells, with a focus on the cell cycle, cell division regulation and how cell size homeostasis is maintained. Research combines cell biology, molecular biology and biochemistry with proteomics, genomics, advanced imaging and cytometry to uncover how decision‑making circuits control when and how cells grow and divide.

Highlighted takeaway: Understanding how cells regulate growth and division reveals fundamental principles of development and disease, including cancer.
