Resource Department is showing wrong in SharePoint 2010

Question

Hello All,
I have one Application which is In-house application (created by our developers) and this is running and hosted on SharePoint 2010. My concern is this I have one user in my application and her Department and Title is showing wrong in site collection. I have
deleted the user from site collection (UIL) and then try to add her name again but still her information is showing wrong. I have checked in Active Directory and all the information is correct there.
Please help me to resolve this issue. Any help will be greatly appreciated.
Many Thanks

Thanks Devendra for your suggestion, but not that much good in codes. Can you please tell me what should I change in the below code to update the fields.
function Sync-SPUser([string]$userName, [string]$title) {
Get-SPSite -Limit All | foreach {
$web = $_.RootWeb
if ($_.WebApplication.UseClaimsAuthentication) {
$claim = New-SPClaimsPrincipal $userName -IdentityType WindowsSamAccountName
$user = $web | Get-SPUser -Identity $claim -ErrorAction SilentlyContinue
} else {
$user = $web | Get-SPUser -Identity $userName -ErrorAction SilentlyContinue
if ($user -ne $null) {
$web | Set-SPUser -Identity $user -SyncFromAD
$list = $web.Lists["User Information List"]
$query = New-Object Microsoft.SharePoint.SPQuery
$query.Query = "<Where><Eq><FieldRef Name='Name' /><Value Type='Text'>$userName</Value></Eq></Where>"
foreach ($item in $list.GetItems($query)) {
$item["JobTitle"] = $title
$item.SystemUpdate()
$web.Dispose()
$_.Dispose()
Appreciate your response on this.
