[Tex/LaTex] Email contact in beamer

Question

I am using \documentclass[9pt]{beamer}.

I put

\title{}
\author{sam \& jony}
\institute{}

Then I want to put email address of authors, how to do so?

Answer 1

How about doing something like:

\documentclass{beamer}
\title{This is my title}
\author[sam \& joey]
       {\parbox[t]{1.5in}{sam \\\texttt{sam@somewhere.edu}} \and 
        \parbox[t]{1.5in}{joey \\  \and \texttt{joey@somewhere.edu}}}
\institute{Somewhere U.}
\begin{document}
\begin{frame}
\titlepage
\end{frame}

\begin{frame}
next
\end{frame}
\end{document}
