My current research mainly focuses on the following two topics.

Firstly, I address the question of whether time must have objective direction. In philosophy of time, there are two major positions; A-theory and B-theory. Although they disagree with various issues, both assume that time must have objective direction. I challenge this assumption by examining various arguments for objective temporal direction, and argue that no such argument succeeds. This was the main topic of my PhD thesis A New Direction for Time.

Second, I explore the possibility of C-theory, according to which there is no objective fact of matter as to which direction is the past and which is the future. Although I believe that C-theory is promising, this view seems to face some serious difficulties. For example, how can we understand claims that appear to presuppose objective temporal directionality, like ‘E is earlier than E*? How can we understand various significant concepts such as causation, agency, change without objective temporal direction? In order to defend C-theory, I tackle with these difficulties.

In addition, I consider various issues concerning temporal direction and temporal passage. These include "Is primitive temporal direction possible?", "Is temporal passage incompatible with B-theory?", "What kind of concept of temporal direction do we endorse?".
