2022 - 2024
Morningstar, Inc.
PI
Project Title: Multi-Objective Financial Portfolio Optimization
Summary: The process of financial portfolio optimization involves choosing the most suitable mix of assets to meet a particular investment goal. Conventional portfolio optimization primarily focuses on maximizing returns and minimizing risks while overlooking the importance of social responsibility or sustainability in financial investments. This project aims to build multi-objective financial portfolio optimization for the investment of mutual funds, where Environmental, Social and Governance (ESG) factors ara additionally taken into consideration. The project is expected to deliver an open-source library for multi-objective financial portfolio optimization, along with strategies for explanations in order to enhance transparency.
Outcomes: the MOPO-LSI library, publications in Software Impacts, ACM COMPASS 2023
2022 - 2024

PI
Project Title: Recommender Systems Based on Deep Learning
Summary: Recommender systems (RecSys) have been developed to alleviate overloaded information and assist users' decison making by delivering a list of recommended items tailored to user preferences. This project aims to build and evaluate effective recommendation models based on the deep learning technologies, particularly for context-aware RecSys, multi-criteria RecSys, multi-objective RecSys.
Outcomes: the DeepCARSKit library, publications in ACM UMAP 2022 and 2023, Software Impacts, IEEE Access, etc.
2020 - 2021
Digby's Detective & Security Agency, Inc.
PI
Project Title: Predictive Staffing Model for Transit Security
Summary: The Chicago Transit Authority (CTA) functions as the entity responsible for overseeing public transportation within Chicago. It is in charge of a majority of the city's bus lines, metro systems, and train services. Digby's security provides services related to reporting crimes or other occurrences. They engage in the monitoring of 151 CTA metro stations and rail yards, strategically deploying their personnel to these areas and documenting any incidents that transpire. The primary objective of this endeavor is to assist Digby's in forecasting the likelihood and locations of potential incidents. This, in turn, allows them to allocate their personnel appropriately, ensuring they are present in the correct place at the right time.
Outcomes: the project establishes a connection between IIT and Digby's, leading to the successful acquisition of multiple internship positions for our students from 2020 to 2022.

Calamos Investments
Partner
Calamos Investments is a diversified global investment firm offering innovative investment strategies including alternative, equity, sustainable, multi-asset, fixed income and convertible strategies. Through the partnership with Calamos Investments, we were able to send several graduate students as interns in the company in 2018. Some students finally acquired full-time positions at this company after their graduation.
