Biography
Wael Houssen is a chemical biologist whose research is centered on the biosynthesis of natural products. His group explores natural compounds with significant medicinal properties, with a particular interest in the enzymatic machinery responsible for their assembly.
The Houssen's Lab identifies, engineer and recruit biosynthetic enzymes as powerful tools for organic synthesis, enabling new and efficient routes to bioactive molecules. The group employs a synergistic approach combining in silico design, synthetic chemistry and in vitro biosynthesis to generate libraries of bespoke challenging-to make compounds.
These compounds serve not only as potential drug leads but also as chemical probes to investigate the molecular mechanisms of drug action within the cell. Dr. Houssen’s research bridges the gap between chemical biology and drug discovery, contributing valuable insight into both fundamental biosynthesis and translational biomedical science.

Research Overview
My research is in the broad areas of chemical and synthetic biology as applied to drug discovery. It involves the identification and biochemical characterization of new enzymes involved in the biosynthesis of modified cyclic peptides. These compounds have high therapeutic potential but are challenging to be synthesised using chemical approaches. I overexpress these enzymes in a bacteria that can be cultured in the lab, engineer and recruit them to produce bespoke modified macrocyclic peptides in vitro. These peptides are in silico designed to interact with challenging targets underlying severe or life threatening diseases e.g. Covid-19, cancer, diabetes and autoimmune disorders. I use variety of assays to test the affinity of these peptides to their targets and use the results to improve the design process.
Our research is very multidisciplinary and involves elements of biochemistry, chemical biology, in silico drug design, peptide solid phase synthesis, genome mining and synthetic biology.
We also have special interest in exploring the therapeutic potential of peptides from animal venoms e.g. scorpions and apply our expertise to produce them and derivatives thereof in quantities sufficient for biological testing.
You can watch this research and Tour our lab in this video. On this lab tour, you'll see how scientists are turning toxins from nature’s fiercest creatures into potential therapeutics against global health threats like COVID-19.
Lab Facilities
My Lab is very well-equipped for molecular biology (PCR, high pressure homogeniser, DNA and protein gel electrophoresis), peptide synthesis (automated microwave peptide synthesiser), chromatography (Agilent HPLC with DAD), Protein purification (two Biorad NGC medium-pressure liquid chromatography systems), microbial fermentation (autoclavable glass bioreactors and shaking and static incubators) and in silico drug design (a dedicated Linux station connected to our supercomputing facility and different software packages).
Lab Members
Our lab is proudly multinational, with members originating from a variety of countries including UK, Egypt, Italy, Poland, Romania, Spain, Iraq, Ghana, Saudi Arabia, Sudan, Sweden, India and Mexico, reflecting the global nature of modern scientific research and collaboration. This cultural and academic diversity strengthens the lab's innovative capacity and fosters a dynamic, inclusive environment for interdisciplinary research.

Knowledge Exchange
Public Outreach
I am an active STEM Ambassador and have organised a variety of outreach activities at schools across Aberdeen, aiming to inspire young people through the wonders of chemistry and chemical biology. My sessions incorporate a wide range of innovative tools, including 3D-printed models, virtual reality, and genetically engineered cells that express colourful proteins. For example, I’ve used these engineered cells to draw images on agar plates- please have a look at my Microbial Art below.
My outreach efforts are inclusive and designed for children of all ages, from nursery pupils to secondary school students, including those with special educational needs. I also engage wider audiences by delivering public lectures at events such as PechaKucha nights.
Below are photos from some of these events.
