Jeyashree Krishnan

Hey there! I am Jeyashree (or JK), thank you for visiting my website. I am a Senior Machine Learning Scientist at Siemens AG. Over the last several years, I have built a career that sits at the intersection of science, consulting, and engineering. My background includes:

  • 10 years of research in numerical simulations
  • 7 years of experience in machine learning
  • 3 years in data science consulting
  • 1 year focused on ML engineering, building scalable ML applications and systems
  • 1 year of focused interest and work in technical AI safety

Currently, I work in Siemens Corporate IT, building ML products and services for the organization. I am also a visiting researcher at the Center for Computational Life Sciences, University Hospital Aachen, where I work on research topics in computational biology. In addition, I conduct independent research in the area of technical AI safety, including adversarial ML, interpretability, and explainability. Outside of work I enjoy running, CrossFit, books, and traveling to new countries.

Professional Expertise

In my current role at Siemens Corporate IT, I build ML products and services that teams across the organization can reliably use. My work focuses on time series foundation models, forecasting, and LLMs, with an emphasis on production-grade ML i.e. scalable pipelines, monitoring, and maintainable systems. I contribute through hands-on technical delivery including designing and implementing ML services and pipelines, improving model quality and monitoring, supporting deployment and operational stability, and reviewing technical designs and code. I also support product direction through roadmap planning, stakeholder management, and technical leadership.

Previously, I worked as a Data Science Consultant at Siemens Advanta Consulting with Dr. Ulli Waltinger, delivering data-driven solutions across domains such as Finance, Cybersecurity, Digital Twin, Healthcare, Sustainability, and more. I led cross-functional projects end to end, from problem framing and stakeholder alignment to model development and delivery. Before industry, I completed my PhD and postdoctoral research at RWTH Aachen University, at Joint Research Center for Computational Biomedicine and Aachen Institute for Advanced Study in Computational Engineering Science with Prof. Andreas Schuppert. My research focused on simulating biological systems and combining model-driven and data-driven methods to understand features that contribute to emergent behavior.

Tools and Technologies

My everyday work involves using a variety of tools and technologies for ML problems. Following are a bunch of tools and technologies I use in my daily work. I built this website with Node.js and Express for the backend and a mix of HTML, CSS, Bootstrap, and JavaScript for the frontend.

Research Work

During my postdoctoral work, I contributed to the Neuronode Project, collaborating with the Ernst Group at McGill University and the Ewing Group at Gothenburg University on computational problems related to neurodegenerative diseases. During my Ph.D., I worked on modeling phase transitions in network biology, combining elements of statistical physics with complex networks. I was a visiting researcher at the Douglas Research Institute / Montreal Neurological Institute at McGill University and the Center for Complex Systems at Utrecht University. For more details, please visit my research page.

Papers, Talks and Industry Contributions

I have had the opportunity to present my work at various international conferences, contribute to industry projects, author whitepapers, and have my research published in reputable journals, gaining valuable experience and insights along the way. Check out my talks and research pages to see more.

Hacking and Tinkering

In my spare time, I work on side projects involving coding and mathematics. I explore topics that interest me and enjoy the process of problem-solving. For more details, please visit my portfolio.

Personal Interests

Outside of work, I enjoy:

  • Running: I have completed over 10 (ultra-) marathons across 6 continents.
  • Traveling: I have visited over 60 countries.
  • Reading: I enjoy reading across various topics.
  • CrossFit: I enjoy lifting weights and doing the WODs.
