Biography

Dr. Hassan is an expert in plant biotechnology and synthetic biology along with extensive research experience and notable achievements in these areas. He obtained a PhD in plant cell and molecular biology (and genetically modified field crops and pastures) from Melbourne University in Australia. His PhD research focused on development of insect resistant GM crops. During PhD, he designed new Bt genes (Bacillus thuringiensis insecticidal toxin protein) requiring minimal licensing cost for humanitarian use. In addition, he designed and tested a novel targeted gene insertion method for plants based on homologous recombination and tested its activity in the model plants Arabidopsis thaliana. During PhD tenure, Dr. Hassan also investigated the ways to improve the efficacy of plant germline transformation method in canola and cabbage. After completing PhD, he joined at Oak Ridge National Laboratory in the United States as postdoctoral research associate in the synthetic biology group where his work focused on plant and microbial synthetic biology. Here, he played a key role in identifying and characterizing plant-derived small-secreted proteins, developing CRISPR-based genome editing tools for bioenergy crops (poplar) and fungi (Laccaria bicolor, Sphaerulina musiva) and improved transformation method for poplar. His postdoctoral work also focused on engineering a synthetic crassulacean acid metabolic (CAM) pathway in plants, a novel CO₂ fixation method in the non-model E. coli bacteria and bioenergy crops poplar and designing artificial leaves. After completing the postdoctoral tenure, Dr. Hassan worked as a research scientist and group lead of molecular biology at a biotech start-up based in Boston that focused on developing cutting-edge peptide-based technologies for managing Citrus greening disease caused by Huanglongbing (HLB) bacteria. Here, he led a team which optimized viability quantitative PCR (vqPCR) method to screen HLB bacteria in Citrus plants. His team has also developed high-throughput DNA extraction and purification and qPCR methods for different applications including screening disease samples, high-throughput cloning. Dr. Hassan’s research on plant genome editing, synthetic biology and genome analysis has generated several novel technologies including biosensors for detecting the activity of different CRISPR/Cas systems in plants, a split base editor for precise plant gene editing, improved transformation and selection method for bioenergy crop poplar, CRISPR/Cas9-RNP-based genome editing tool for non-model fungi Sphaerulina musiva. Dr. Hassan’s research has also been featured in international news media including Global Plant Council,ScienceDaily, Phys.Org.

Research Interest

My interests lie at the intersection of agricultural science and biotechnology, with a primary focus on addressing critical challenges in crop improvement and sustainable agriculture. My work centers around the intricate mechanisms of plant biology, employing cutting-edge techniques in biological engineering to develop innovative solutions for global agricultural issues. My current research includes:

1. Rice Domestication for Salt Tolerance:

One of my key research interests revolves around enhancing the salt tolerance of rice, a staple food for a significant portion of the world's population. Through a multidisciplinary approach, I aim to decipher the genetic and physiological basis of salt tolerance in rice varieties. By identifying and manipulating key genes involved in this trait, my research strives to contribute to the development of salt-resistant rice varieties that can thrive in saline soils, thereby bolstering food security in regions affected by salinity.

2. CO2 Fixation Using Biological Engineering:

Addressing the pressing issue of climate change, my research delves into the realm of biological engineering for carbon dioxide (CO2) fixation. With a focus on harnessing the potential of plants and microorganisms, I aim to develop novel strategies for efficient CO2 sequestration. By leveraging the inherent biological processes of photosynthesis and exploring biotechnological interventions, my work aims to mitigate the impact of greenhouse gas emissions and contribute to the development of sustainable solutions for a rapidly changing climate.

3. Fixation of Hybrid Vigor in Plants:

Hybrid vigor, or heterosis, represents a phenomenon where the offspring of genetically diverse parents exhibit superior traits compared to their parents. My research explores the mechanisms underlying hybrid vigor in plants, with a specific emphasis on understanding the genetic and epigenetic factors that contribute to this phenomenon. By unraveling the complexities of hybrid vigor, I seek to develop strategies for stabilizing and fixing these beneficial traits in plant populations, ultimately enhancing crop yields and agricultural productivity.

New biosensors shine a light on CRISPR gene editing.

Detecting the activity of CRISPR gene editing tools in organisms with the naked eye and an ultraviolet flashlight is now possible using technology developed at the Department of Energy's Oak Ridge National Laboratory. Scientists demonstrated these real-time detection tools in plants and anticipate their use in animals, bacteria and fungi with diverse applications for biotechnology, biosecurity, bioenergy and agriculture. The team described the successful development of the UV system in Horticulture Research and their proof-of-principle demonstration in ACS Synthetic Biology.

CRISPR technologies have quickly become the primary tools of bioengineering, and new versions are continually in development. Identifying whether an organism has been modified by CRISPR technology was previously a complex and time-consuming process. Before this, the only way to tell if genome engineering occurred was to do a forensic analysis," said Paul Abraham, a bioanalytical chemist and head of ORNL's Secure Ecosystem Engineering and Design Science Focus Area. "To be successful, you would need to know what the genome looked like before it was rewritten. We wanted to design a platform where we could proactively observe CRISPR activity."

The research team developed an efficient self-detect solution that takes advantage of the way CRISPR works to trigger the technology to reveal itself. Under normal conditions, CRISPR works by connecting with a short RNA sequence, known as the guide RNA, as it leads CRISPR to a matching DNA sequence. When the target DNA is found, CRISPR modifies the DNA by acting like tiny molecular scissors to cut through one or both strands of DNA, depending on the type of CRISPR technology in use. Abraham likens their method to an alarm system with two components: a biosensor guide RNA that redirects CRISPR activity and a reporter protein that flags the activity. Researchers encode the two components into an organism's DNA to enable the monitoring system. With the self-detect system in place, the biosensor guide RNA intercepts CRISPR, preventing CRISPR from connecting with its original gene target and redirecting CRISPR to a specific DNA sequence that encodes for a nonfunctioning green fluorescent protein, or GFP. When CRISPR edits the sequence, it flips a switch that produces functioning GFP, which creates a green glow signaling CRISPR's presence.
