Wolfgang Busch

Professor and Director
Plant Molecular and Cellular Biology Laboratory
Integrative Biology Laboratory

Wolfgang did his undergraduate studies in Biology at the University of Tübingen, Germany. During this time, he also spent 8 months at UC San Diego where he received training on computational biology and conducted research on transporter proteins. During his PhD at the Max Planck Institute for Developmental Biology in Tübingen, he identified novel key regulatory genes and modules for plant stem cell control via a systems biology approach integrating transcriptome- and genome-scale transcription factor-DNA binding data. Wolfgang received his PhD in 2008 from the University of Tübingen. During his postdoctoral training at Duke University he contributed to the discovery of spatiotemporally defined regulatory modules that control proliferation of stem cells and differentiation in the root, and used high-throughput confocal microscopy to capture dynamic features of gene expression. In 2011, he joined the Gregor Mendel Institute of Molecular Plant Biology in Vienna as a group leader. During this time, he established his research program in root systems genetics and focuses on understanding which genes, genetic networks, and molecular processes determine root growth and its responses to the environment. In 2017, he came to the Salk as an Associate Professor in the Plant Molecular and Cellular Biology Laboratory. He is also part of the Integrative Biology Laboratory. A recent key interest of Wolfgang is researching and developing plant varieties with enhanced carbon sequestration capabilities for removing CO2 from the atmosphere and thereby counteracting climate change.
Postdoctoral Fellows
Elohim-Bello-Bello-v2

Elohim Bello Bello

Postdoctoral Fellow

Elohim earned his PhD at the National Laboratory of Genomics for Biodiversity (LANGEBIO-CINVESTAV) in Mexico, where he contributed to the identification of genomic regions and candidate genes underlying natural variation in primary root penetrability in Arabidopsis thaliana. His research focuses on leveraging multi-omics strategies to unravel how gravitropic and thigmotropic responses influence root penetration into compacted soils. He is particularly interested in decoding the genetic and molecular mechanisms that drive natural variation in root system penetrability to enhance deep rooting and CO? sequestration in crop plants. Elohim joined the Busch lab in 2022 as a part of the Harnessing Plants Initiative at the Salk Institute. He and his colleagues are focused on designing new high-throughput phenotyping platforms and creating root-targeted genetic engineering approaches to develop smart-rooting crops better adapted to land degradation and climate change.

Maurizio-Chiurazzi

Maurizio Chiurazzi

Visiting Scientist

Originally from Naples, Italy, Maurizio obtained his PhD at the University of Copenhagen. He studied microProteins in plants and the ways they can be used to control plant developmental processes in Arabidopsis and Alfalfa, with a focus on flowering time. In his first Postdoc in Copenhagen, he focused on genome engineering in Alfalfa and on optimizing the crop’s transformation and regeneration procedures. After obtaining a Marie Curie Global Postdoc Fellowship, he joined the Busch Lab in October 2025. As part of the Lab and of the Harnessing Plants Initiative, he will work on transferring to Alfalfa the knowledge acquired throughout the years within HPI (with a microProtein twist), while also identifying novel candidates contributing to deeper, steeper root systems. Maurizio loves dogs, pop culture, hiking, dancing, exploring new places and is super excited about getting to know San Diego and California, together with his husband.
laurence-denis

Laurence Denis

Postdoctoral Fellow

Originally from France, Laurence obtained her PhD in the Laboratoire Mixte CNRS/Aventis CropScience (UMR 41) in Lyon, France. She studied the biotinylation of proteins in Arabidopsis thaliana and uncovered the molecular mechanisms explaining the compartmentalization of biotin ligase activity in the cell. After two post-docs focusing on cell cycle regulation in mammalian cells (in Cold Spring Harbor Laboratory, and in Sanford Burnham Prebys in San Diego), she decided to go back to plant science studies and joined the Busch lab. As a member of HPI, she will be designing genetic tools to foster steeper roots in plants.
Huani Liao

Huan Liao

Postdoctoral Fellow

Huan received her PhD from China Agricultural University, where she identified an E3 ubiquitin ligase as a key regulatory hub linking cold stress responses and phosphate uptake in maize. By integrating AI-assisted protein design and genome editing, she engineered the protein to overcome the trade-off between cold tolerance and phosphate acquisition and improve yield under cold conditions.

She joined the Salk Institute as a Postdoctoral Fellow in 2026. Her current research focuses on uncovering the molecular mechanisms regulating root system architecture and its developmental plasticity in response to fluctuating water and nutrient availability, with the ultimate goal of designing climate-smart crops (e.g., soybean and maize) and contributing to sustainable agriculture. Outside the lab, she enjoys playing sports, hiking, and exploring new places.
suyash-patil

Suyash Patil

Postdoctoral Fellow

Originally from India, Suyash Patil received his PhD at the Chinese Academy of Agricultural Sciences, Beijing, China in 2019. During his PhD studies, he worked on the molecular basis of plant architecture regulation focusing on the plant hormone auxin and its crosstalk with strigolactones and sucrose signaling. Before joining the PhD program, he worked at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) as a pigeon pea breeder. Patil contributed actively to the development of high-yielding, disease-resistant pigeon pea varieties, and hybrids for different ecologies. Patil worked at the International Rice Research Institute (IRRI) based in India to work on developing climate-smart dry direct seeding (DSR) friendly rice varieties. He joined the Busch lab in October 2022 with a focus on improving rice root traits for enhanced nutrient uptake and carbon capture capabilities for yield and climate resilience.
Feng Qin

Feng Qin

Postdoctoral Fellow

Feng received her Ph.D. from Kunming Institute of Botany, Chinese Academy of Sciences in 2020, where she studied flowering time and seed ageing in Arabidopsis. After one post-doc in Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, she decided to go back to plant science studies and joined the Busch lab in November of 2022. Her interest here is how roots respond to stresses and regulation of the meristem under stresses. Outside the lab, she likes hiking, jogging, watching movies and making friends.
denghui-wang

Denghui Wang

Postdoctoral Fellow

Denghui received his PhD from the State Key Laboratory of Hybrid Rice, Wuhan University in 2026. During his PhD, he focused on identifying new key genes involved in thermo-perception in plants. By integrating molecular biology, biochemistry, and omics methods, he has identified a conserved protein that can perceive high temperature by phase transition. His research interest is to understand how plants perceive and adapt to the environment. In the Busch lab, he will continue to investigate the molecular mechanism underlying the interaction between iron deficiency and immune responses. Beyond the lab, he enjoys hiking, cycling, and listening to supernatural podcasts.

Charlotte Miller

Research Scientist

Charlotte received her Ph.D. from the John Innes Centre (UK), where she explored natural variation in stem mechanical properties in wheat and canola. She continued at John Innes for her postdoctoral research, focusing on seed yield in canola. Using Associative Transcriptomics, she identified UPL3 as a novel regulator of seed filling—discovering that loss-of-function mutants showed a 20% increase in seed yield.

Charlotte is currently a Research Scientist at the Salk Institute, where she applies GWAS and single-nucleus RNA sequencing to investigate the developmental biology of the root periderm. As part of this work, she recently led the publication of the first single-nucleus RNA-seq atlas capturing multiple stages of periderm development at unprecedented resolution.

Beyond the lab, Charlotte plays in several local bands and enjoys all things creative. She’s recently fallen in love with snorkeling and spends her free time fostering senior dogs.

Ashish Rajurkar

SR RESEARCH SCIENTIST

Ashish received his PhD from Tamil Nadu Agricultural University, India, while collaborating with the International Rice Research Institute (IRRI), Philippines, and with Duke University, USA. During his PhD. research, he was able to identify and map consistent QTLs for root traits and yield under drought. He was also involved in developing thicker and deeper drought-resilient root lines in Rice under target rainfed environments in India. After these discoveries, he moved to the United States to continue his root research. During his post-doctoral study at the University of Illinois at Urbana-Champaign, Ashish studied root system size and distribution in Maize under nitrogen-deficient conditions. He also looked at how to best utilize large-scale Minirhizotrons, a multimodality phenomics approaches to phenotype root traits in field-based settings, and how to better understand the functional consequences of nutrient uptake. He then moved to the University of Missouri, Columbia to study Switchgrass, a promising bioenergy crop, and how it could be adapted to different environmental conditions with diverse root systems. Ashish has an interest in climate-smart agriculture and will be working on Soybean and Canola. He will be studying their root traits in hopes of increasing root depth, increasing soil carbon, improving soil health, and maximizing the water storage potential of soils.
