[Tex/LaTex] Beamer – Multiple Authors – Formatting the title page

beamertitles

I have 4 authors for the beamer presentation. I tried to put them but its not properly aligned. Here is a snapshot:

Here is the MWE:

\documentclass{beamer}
\usetheme{CambridgeUS}
\useoutertheme{infolines}
\author[Subham Soni S. \& Mithun C.K. \& Karthikeyan \& Shantikumar L.]
{%
   \texorpdfstring{
        \begin{columns}
            \column{.45\linewidth}
            \centering
            Subham Soni S.\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}
            \column{.45\linewidth}
            \centering
            Mithun C.K.\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}
            \column{.45\linewidth}
            \centering
            Karthikeyan\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}
            \column{.45\linewidth}
            \centering
            Shantikumar L.\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}
        \end{columns}
   }
   {John Doe \& Jane Doe}
}
\title{Work Culture}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\end{document}

If the authors can be arranged vertically I feel that would be better and down below in the pdf in the 3 boxes , the author names are concatenated in the first box, I saw in of the beam ppts that the authors were separated in another row. How to do that ?

This is another possible layout:

\documentclass{beamer}
\usetheme{CambridgeUS}
\useoutertheme{infolines}
\usepackage{tikz}
\newcommand\RBox[1]{%
  \tikz\node[draw,rounded corners,align=center,] {#1};%
}  
\author[Subham Soni S. \& Mithun C.K. \& Karthikeyan \& Shantikumar L.]
{%
   \texorpdfstring{
        \begin{columns}
            \column{.45\linewidth}
            \centering
            \RBox{Subham Soni S.\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}}
            \column{.45\linewidth}
            \centering
            \RBox{Mithun C.K.\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}}
        \end{columns}
        \vspace{0.5cm}
        \begin{columns}
            \column{.45\linewidth}
            \centering
            \RBox{Karthikeyan\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}}
            \column{.45\linewidth}
            \centering
            \RBox{Shantikumar L.\\
            \href{mailto:subhamsoni0049@pec.edu}{subhamsoni0049@pec.edu}}
        \end{columns}
        \vspace{-0.3cm}
        \begin{columns}
          \column{0.3\linewidth}
          \raggedleft
            \includegraphics[width=0.7cm]{pecemblem}
            \vspace{-4.8cm}
            \column{0.6\linewidth}
            \raggedright
            Department of CSE\\[1.1ex]
            PEC\\
            \vspace{-4.8cm}
        \end{columns}
   }
   {John Doe \& Jane Doe}
}
\title{Work Culture}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\end{document}

Adding these lines to the definition of \RBox

\usetikzlibrary{shadows}
\newcommand\RBox[1]{%
  \tikz\node[draw,rounded corners,align=center,double copy shadow={opacity=0.3,shadow xshift=1ex,shadow yshift=-0.5ex,left color = brown!40,right color = magenta!80},left color=blue!50,right color=green!50 ] {#1};%

gives
