Westerholm is a former trading professional whose teaching and research interests center on asset pricing with a focus on security market microstructure and behavioral finance.

His research spans multiple sub-fields in financial economics. In asset pricing, it investigates the pricing implications of individual investor trading behavior and dynamics of order flow. In market microstructure, the research addresses liquidity provision, dark trading, and trading mechanism design. In behavioral finance, it explores the impact of investor sentiment and biases on asset prices. He has received funded research grants and supervises research-based degrees such as Essays in Asset Pricing. Westerholm teaches finance courses at the University of Sydney. His work contributes to understanding trading dynamics, investor decision-making, and market efficiency.

Prominent among his publications is the book Lecture Notes in Market Microstructure and Trading, published by World Scientific in 2018, intended as a basis for courses in market microstructure by connecting theoretical rigor with practical trading experience. Key journal articles include Investor Behavior at the 52-Week High in the Journal of Financial and Quantitative Analysis (2022), which shows how household investors intensify the 52-week high effect on volume and momentum-like returns; Information Processing Skills of Short Sellers (2021); Speculative Trading Preferences of Retail Investor Birth Cohorts in Accounting & Finance (2022); and Price Discovery and Success Factors for Individual Stock Futures in the International Journal of Bonds and Derivatives (2013). These publications reflect his influence on empirical finance research.
