I'm a doctoral candidate interested in affective science, complex systems, and self-regulation
Every day, we rely on billions of years of biochemical evolution to perceive the environment and behave adaptively. Sometimes the means to fulfill our physiological and psychological needs fall beyond our volitional sphere of control, but the ways in which we appraise these events and select subsequent situations shape what follows. In my research, I investigate how people influence their perception and semi-automatic processes such as emotion to lead more deliberate lives.
Emotional Dynamics of Situation Selection
I'm investigating the role of situation selection as a dynamic sequencing control problem. How do agents adaptively arrange emotional experiences to pursue internal needs under changing constraints? I frame situation selection as a state-dependent, value-guided decision process under uncertainty, in which momentary affect, learned values, and available options interact recursively over time to order emotional inputs in ways that reflect current goals. This framework integrates insights from emotion regulation, affective forecasting, and reinforcement learning into a unified control-based account of how emotional trajectories are shaped before emotions unfold.
Across a series of controlled behavioral experiments, I show that situation selection is systematic, state-dependent, and multiply determined. People do not simply seek pleasure or avoid discomfort. Instead, current affect reliably biases which emotional experiences people want next, including their appetite for arousal, challenge, and informational value. Crucially, this work distinguishes short-term effectiveness from long-term adaptiveness: strategies that reduce immediate distress can impair learning, flexibility, and future regulation capacity, producing maladaptive trajectories across repeated decisions.
Methodologically, my work combines tightly controlled experimental paradigms with formal models of behavioral choice. I study prospective approach-avoid decisions over emotional stimuli to isolate forecasting, uncertainty, and within-person state effects. Analytically, I use multilevel models, mediation analyses, and computational modeling to characterize how forecasted valence, interest, and motivational state jointly shape choice. The result is a mechanistic, process-level account of how emotional environments are selected, and how repeated selections accumulate to shape emotional life over time.
Automating Motivational Interviewing
In this line of work, I take the premise that lasting
behavioral change depends less on effortful self-control
than on reshaping underlying desires (Inzlicht & Roberts,
2024), and I test whether theoretically constrained AI can
scaffold that process through structured dialogue.
In a preregistered randomized controlled trial, I developed and tested an AI-based motivational interviewing system, designed with motivational interviewing therapists, that guided participants through a semi-structured conversation about becoming more prosocial. We found that a single brief interaction reliably increased motivational readiness (importance, confidence, and readiness to act), demonstrating that MI-consistent mechanisms can be implemented via automated dialogue. Critically, these effects were short-lived and did not translate into behavioral change, establishing clear boundary conditions.
Current work is aimed at pushing these boundaries, but for now we conclude that automated motivational interviewing can move state motivation in the moment, whereas durable change likely requires repeated interventions. This work positions AI not as a replacement for therapy, but as a potential supplement, and as a precise experimental tool for testing mechanisms of dialogue-driven change at scale (Eiroa-Solans & Inzlicht, 2025).

What is emotion?
I'm very interested in the idea that emotions are relational drives acting as internal control signals that predictively drive adaptive behaviors to prototypically different situations.
I'm considering a research program that traces how emotion dynamics reshape valuation, bias the next action, and influence the environments people choose to enter. That means asking concrete questions like: which emotional states widen versus narrow the space of options, when do they promote exploitation versus exploration, and how do they steer people toward safety, status, connection, novelty, or control?
Formalizing this control loop should yield testable predictions about when emotions support flexible adaptation, and when the same signal becomes a trap, driving self-reinforcing cycles like rumination, avoidance, or compulsion that steer people away from well-being.
Dreams and Memory Integration
For over a decade, I've kept a daily written record of my dreams and waking life. Recently, it dawned on me that I've accumulated a longitudinal corpus of roughly 7,000 dreams, which is an unusually dense record of how lived experience might get transformed into nocturnal cognition. This made me wonder: is there any relationship between the two? Are some features more predictive than others? On what time scales do these predictions operate?
Rather than treating dreams as symbols to be interpreted, I am thinking about them as compressed, affect-laden traces of recent experience on their way to becoming memories. Using computational text analysis and embedding-based models, I am planning to treat waking experiences as inputs and subsequent dreams as outputs, asking whether (and when) features of daily emotional life show up in dream content.
I'm currently in the unglamorous phase of cleaning and structuring the data. If you have ideas for analyses, or strong opinions about dreams, memory, or how much structure the sleeping mind imposes on waking life, please reach out!
