Himabindu "Hima" Lakkaraju is an Assistant Professor of Business Administration at Harvard Business School. She is also a faculty affiliate in the Department of Computer Science at Harvard University, the Harvard Data Science Initiative, Center for Research on Computation and Society, and the Laboratory of Innovation Science at Harvard. She teaches the first year course on Technology and Operations Management, and has previously offered multiple courses and guest lectures on a diverse set of topics pertaining to Artificial Intelligence (AI) and Machine Learning (ML), and their real world implications.
Professor Lakkaraju's research focuses on the algorithmic, practical, and ethical implications of deploying AI models in domains involving high-stakes decisions such as healthcare, business, and policy. More specifically, she studies the design and deployment of AI models that are explainable (readily understandable to decision makers), fair (do not discriminate against minority groups), and more broadly reliable when deployed in the real world. She leads the AI4LIFE research group at Harvard University as part of which she supervises multiple postdoctoral, graduate, and undergraduate students. Professor Lakkaraju’s research has been published in top AI and ML conferences including the International Conference on Machine Learning (ICML), Advances in Neural Information Processing Systems (NeurIPS), the AAAI Conference on Artificial Intelligence, and International Conference on Artificial Intelligence and Statistics (AISTATS), as well as prestigious interdisciplinary journals such as Quarterly Journal of Economics (QJE).
Her research has been felicitated with multiple best paper awards including the INFORMS Best Data Mining Paper Prize and the SIAM International Conference on Data Mining (SDM) Best Research Paper Award. She also received prestigious grants from the National Science Foundation (NSF), and various research awards from Google, Amazon, and Bayer. Her research has also been covered by various popular media outlets including the New York Times, MIT Tech Review, Harvard Business Review, TIME magazine, Forbes, Wired, and VentureBeat. Professor Lakkaraju was also named one of the world's top Innovators Under 35 by both Vanity Fair and the MIT Technology Review.
In addition to her research, she is passionate about advising startups in the space of AI/ML, and making the field of AI/ML more accessible to the general public. She advises the research and product strategy of Fiddler AI, one of the most sought after startups in the field of responsible AI. Professor Lakkaraju also co-founded the Trustworthy ML Initiative (TrustML) to lower entry barriers, promote discussion and debate on latest developments, and build a community of researchers, practitioners, and policy makers working on AI and its real world implications. As part of this initiative, Lakkaraju has developed various accessible, publicly and freely available tutorials on several aspects of AI and ML. She has also started a virtual talk series where renowned experts (both in AI/ML and other domains such as healthcare, business, and policy) discuss their research and anyone in the world can attend these talks and interact with these experts.
Professor Lakkaraju received her PhD and MS degrees in computer science from Stanford University. Prior to her stint at Harvard Business School, she has held various positions at Microsoft Research, IBM Research, and Adobe.

- Research Summary
-
I develop machine learning tools and techniques which enable human decision makers to make better decisions. More specifically, my research addresses the following fundamental questions pertaining to human and algorithmic decision-making:
1. How to build fair and interpretable models that can aid human decision-making?
2. How to ensure that models and their explanations are robust to adversarial attacks?
3. How to train and evaluate models in the presence of missing counterfactuals?
4. How to detect and correct underlying biases in human decisions and algorithmic predictions?
These questions have far-reaching implications in domains involving high-stakes decisions such as criminal justice, health care, public policy, business, and education.The goal of this research is to assess the impact of deploying machine learning models in real world decision making in domains such as health care.I work on developing various tools and methodologies which can help decision makers (e.g., doctors, managers) to better understand the predictions of machine learning models.The goal of this research is to understand how adversaries can exploit various algorithms used for explaining complex machine learning models with an intention to mislead end users. For instance, can adversaries trick these algorithms into masking their racial and gender biases?The goal of this research direction is to ensure that the machine learning models we build and deploy do not discriminate against individuals from minority groups.The goal of this research is to ensure that machine learning models that we build and deploy are not easily susceptible to attacks by adversarial or malicious entities. - Teaching

As machine learning models are increasingly being employed to aid decision makers in high-stakes settings such as healthcare and criminal justice, it is important to ensure that the decision makers correctly understand and consequent trust the functionality of these models. This graduate level course aims to familiarize students with the recent advances in the emerging field of explainable ML. In this course, we will review seminal position papers of the field, understand the notion of model interpretability from the perspective of various kinds of end users (e.g., doctors, ML researchers/engineers), discuss in detail different classes of interpretable models and model explanations (e.g., case/prototype based approaches, sparse linear models, rule-based techniques, saliency maps, generalized additive models, and counterfactual explanations), and explore the connections between model interpretability and fairness, robustness, causality and debugging. The course will also emphasize on various applications which can immensely benefit from model interpretability including medical and judicial decision making.
The course will comprise of a mix of lectures by instructor, paper presentations by students, and guest lectures by researchers who have authored seminal papers on this topic. This course has a significant research component in the form of a course project that students will be expected to work on through out the semester. All in all, this course is geared towards those students who are interested in diving deep and conducting research in the field of interpretable and explainable ML.
This course enables students to develop the skills and concepts needed to ensure the ongoing contribution of a firm's operations to its competitive position. Topics include digital marketplaces, technology, and data science.
I taught a set of lectures on "Introduction to Machine Learning for Social Scientists" as part of this required course for first year PhD students. This module familiarizes students with all the basic concepts in machine learning, their implementations, as well as the real world challenges encountered when building and deploying machine learning models.
Topics encompass:
Supervised learning
Unsupervised learning
Reinforcement learning
Practical Challenges: overfitting, data imbalance, missing counterfactuals
Making machine learning models fair, interpretable, and robust - Awards & Honors
