Problem
I am now updating my resume and I found tasks package is a good choice to list my research interests in the same line (which could save a lot of space). Even though I basically got what I want, it seems that three items I list did not have same horizontal space and this makes it a little unsatisfactory.
What I Have Done
I checked the doc of the tasks package and especially the figure shown below, but it seems that we could not restrict the text width of each bullet point.

Did I miss something? Any input is appreciated.
MWE
\documentclass{article}
% EDIT
\usepackage[margin=0.5in, nohead]{geometry}
\usepackage{tasks}
\settasks{item-indent=3em, label-offset=0em, column-sep=2em}
\begin{document}
\begin{tasks}[style=itemize](3)
\task Gaussian process machine learning \task Statistical learning theory \task (Non)-convex optimization
\end{tasks}
\end{document}


taskspackage exist, but I find it pretty ugly. – Mr.Robot Mar 30 '19 at 01:08\hspace{1em}\textbullet~~Gaussian process machine learning\hfill \textbullet~~Statistical learning theory\hfill \textbullet~~(Non)-convex optimization\hspace{1em}\par? – Mar 30 '19 at 02:34
